Question

Given the information below that includes the sample size (n1 and n2) for each sample, the mean for each sample (x1 and x2) and the estimated population standard deviations for each case( σ1 and σ2), enter the p-value to test the following hypothesis at the 1% significance level :

Ho : µ1 = µ2

Ha : µ1 > µ2  

Sample 1	Sample 2
n1 = 10	n2 = 15
x1 = 115	x2 = 113
σ1 = 4.9	σ2 = 5.2

What is the p-value for this test ?

Given the information below that includes the sample size (n1 and n2) for each sample, the mean for each sample (x1 and x2) and the standard deviations for each sample (s1 and s2), enter the p-value to test the following hypothesis at the 1% significance level . Assume the variables come from normally distributed populations with equal variances

Ho : µ1 = µ2

Ha : µ1 < µ2  

Sample 1	Sample 2
n1 = 12	n2 = 12
x1 = 113	x2 = 115
s1 = 4.2	s2 = 5.15

What is the p-value for this test ?

Please breakdown the answer.
