Question: Consider the following hypothesis statement using = 0.10 and data from two independent samples. Assume the population variances are not equal and the populations

Consider the following hypothesis statement using α = 0.10 and data from two independent samples. Assume the population variances are not equal and the populations are normally distributed.

xi = 144.0 s,=16.8 n1 = 27 x2-1563 s,27.0 n2 = 21

a. Calculate the appropriate test statistic and interpret the result.

b. Approximate the p value using Table 5 in Appendix A and interpret the results.

c. Determine the precise p value using Excel.

d. Verify your results using PHStat.
