Any excel formula or words to get final answer so I can repeat process would be helpful, thank you.
You wish to test the following claim (H) at a significance level of a = 0.05. H:H1 = 42 H:H1 H2 You believe both populations are normally distributed, but you do not know the standard deviations for either. However, you also have reason to believe the variances of the two populations are not equal. You obtain a sample of size ni = 14 with a mean of M1 = 51.2 and a standard deviation of SD= 8.2 from the first population. You obtain a sample of size na = 23 with a mean of M2 = 62.2 and a standard deviation of SD2 = 13.4 from the second population. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = 1 What is the p-value for this sample? For this calculation, use the conservative under-estimate for the degrees of freedom as mentioned in the textbook. (Report answer accurate to four decimal places.) p-value = The p-value is...
