Runger Norma F. DOWNLOAD PDF. However, in working problems by hand, it is useful to be able to find the P-value for a t-test. Because the t-table in Appendix A Table II contains only 10 critical values for each t distribution, determining the exact P-value from this table is usually impossible.
The relevant critical values from Appendix A Table II are as follows: Approximating the P-Value for a t-Test Using Minitab to Calculate the P-Value Critical Value: Tail Area: 0. Therefore, the P-value must be between 0. Refer to Fig, engineering statistics 5th edition pdf download. These are effectively the upper and lower bounds on the P-value.
This illustrates the procedure for an upper-tailed test. If the test is lower tailed, just change the sign on the lower and upper bounds for t0 and proceed as above. Remember that for a two-tailed test, the level of significance associated with a particular critical value is twice the corresponding tail area in the column heading. This consideration must be taken into account when we compute the bound on the P-value. The value of the test statistic t0 7 2. Some statistics software packages can help you calculate P-values.
For example, Minitab has the capability to find cumulative probabilities from many standard probability distributions, engineering statistics 5th edition pdf download, including the t distribution. On the Calc menu select the t distribution and enter the value of the test statistic t0 along with the appropriate number of degrees of freedom. From the cumulative probability the P-value can be determined. The single-sample t-test we have just described can also be conducted using the fixed significance level approach.
Consider the two-sided alternative hypothesis. As we noted earlier, the t-test is relatively robust to the assumption of normality. That is, small to moderate departures from normality have little effect on the procedure. You can always use a normal probability plot to check the normality assumption, engineering statistics 5th edition pdf download. EXAMPLE Golf Clubs The increased availability of light materials with high strength has revolutionized the design and manufacture of golf clubs, particularly drivers.
Clubs with hollow heads and very thin faces can result in much longer tee shots, especially for players of modest skills. Firing a golf ball at the head of the club and measuring the ratio of the outgoing velocity of the ball to the incoming velocity can quantify this spring-like effect. The ratio of velocities is called the coefficient of restitution of the club.
An experiment was performed in which 15 drivers produced by a particular club maker were selected at random and their coefficients of restitution measured. Engineering statistics 5th edition pdf download the experiment the golf balls were fired from an air cannon so that the incoming velocity and spin rate of the ball could be precisely controlled.
The observations follow: 0. The normal probability plot of the data in Fig. Because the objective of the experimenter is to demonstrate that the mean coefficient of restitution exceeds 0. The solution using the seven-step procedure for hypothesis testing is as follows: 1. We want to reject H0 if the mean coefficient of restitution exceeds 0. Reject H0 if: Reject H0 if the P-value is smaller than 0. Because this is a one-tailed test we know that the P-value is between those two values.
That is, 0. To use Minitab to compute the P-value, use the Calc menu and select the probability distribution option. Practical engineering conclusion: There is strong evidence that this type of golf club engineering statistics 5th edition pdf download a coefficient of restitution greater than 0. If this is a specification or limiting value, the club manufacturer may have to modify the design.
We will give the confidence bound formulas in Section However, recalling the discussion in Section Minitab also calculates a P-value for the test statistic T0. Animation 9: Hypothesis Testing for Averages Because the noncentral t-random variable has a messy density function, this integration must be done numerically. These graphics are called operating characteristic or OC curves. Curves are provided for two-sided alternatives in Charts Va and Vb.
We can avoid this difficulty in several ways. EXAMPLE Golf Clubs Consider the golf club testing problem from Example If the mean coefficient of restitution differs from 0. The following display shows several calculations based on the golf club testing problem. In the middle section of the output, we asked Minitab to compute the power if the difference in means we wanted to detect was 0. The third section of the output is the sample size required to give a power of at least 0.
These formulas are given in the table on the inside front cover. EXAMPLE Golf Clubs Reconsider the golf club coefficient of restitution problem in Example Some engineers might be interested in a one-sided confidence bound.
Recall that the Minitab output actually computed a lower confidence bound. This is also the result reported by Minitab. Consider the Minitab output shown below. Can the null hypothesis be rejected at the 0. b Is this a one-sided or a two-sided test? b Fill in the missing information. Consider the Minitab output below. a How many degrees of freedom are there on the t-test statistic? You may calculate bounds on the P-value. The data follow. b Do the data have an approximately normal distribution?
Provide a graphical display to support your answer. d What sample size would be required to detect a true mean speed-up time of 4. An article in the ASCE Journal of Energy Engineering Vol, engineering statistics 5th edition pdf download. Five samples of the material were tested in a structure, and the average interior temperature °C reported was as follows: Use the P-value approach, engineering statistics 5th edition pdf download.
b Check the assumption that interior temperature is normally distributed. d What sample size would be required to detect a true mean interior temperature as high as A research engineer for a tire manufacturer is investigating tire life for a new rubber compound.
She has built 10 tires and tested them to end-of-life in a road test. The sample mean and standard deviation are 61, and kilometers, respectively. a The engineer would engineering statistics 5th edition pdf download to demonstrate that the mean life of this new tire is in excess of 60, km.
Formulate and c04DecisionMakingforaSingleSample. b Suppose that if the mean life is as long as 61, km, the engineer would like to detect this difference with probability at least 0. d Use the bound found in part c to test the hypothesis. An Izod impact test was performed on 20 specimens of PVC pipe. The ASTM standard for this material requires that Izod impact strength must be greater than 1.
State any necessary assumptions about the underlying distribution of the data. The life in hours of a biomedical device under development in the laboratory is known to be approximately normally distributed. A random sample of 15 devices is selected and found to have an average life of a Test the hypothesis that the true mean life of a biomedical device is greater than using the P-value approach. c Use the confidence bound found in part b to test the hypothesis.
A particular brand of diet margarine was analyzed to determine the level of polyunsaturated fatty acid in percent. A sample of six packages resulted in the following data: a It is important to determine if the mean is not Test an appropriate hypothesis, using the P-value approach.
