Assume that you have a sample of n1=4 , with a sample mean Xbar1 = 50 , and a sample standard deviation of S1= 5, and you have an independant sample of n2 = 8 from another population with a sample mean Xbar2 = 32 and the sample standard deviation S2=6. Assuming the population variances are equal, at the 0.01 level of significance, is there evidence that μ1>μ2?

part a

determine the hypotheses

a- Ho: μ1 not equal μ2 , H1: μ1= μ2?

b- Ho: μ1 less than or equal to μ2 , H1: μ1 greater than μ2

c- Ho:μ1 greater than μ2 , H1: μ1 less than or equal than μ2

d- Ho: μ1 = μ2 , H1: μ1 not equal to μ2

part b

what is the test statistic?

what is the p value?

part c

what is your statistical decision?
