On the basis of this p-value we would reject the null hypothesis and accept the research hypothesis that the variances are unequal. There is additional output that is given as shown in Fig. 1-14. The upper part of Fig. 1-14 gives the confidence interval in graphic form.

To find the p-value, we find the area in the left tail and double it. The pull-down Calc ) Probability Distributions ) t gives the dialog box shown in Fig. I-20. We fill it as shown. 1. 065. Fig. I-19. Introduction 24 Fig. I-20. EXAMPLE I-16 An upper-tailed hypothesis test of a population variance is conducted and the computed test statistic is equal to 10. The test statistic is computed from a small sample of size n ¼ 6. Draw a chi-square curve illustrating the p-value. Calculate the p-value. SOLUTION The graph illustrating the p-value is shown in Fig.

5,0) is entered into B1. A click-and-drag is performed on both columns. In the NORMDIST function, the 0 in the fourth position tells Excel to calculate the height of the curve at the number in the first position. Suppose we wished to know the percent of males who are taller than 6 ft 3 inches. 9452. This is the percent that are shorter than 75 inches. The 1 in the fourth position of the NORMDIST function tells Excel to accumulate the area from 75 to the left. 48% that are taller than 75 inches.
