Find the critical values, t0, to test the claim that μ1 = μ2. Two samples are random, independent, and come from populations that are normal. The sample statistics are given below. Assume that .

n1 = 25 n2 = 30

1 = 25 2 = 23

s1 = 1.5 s2 = 1.9

Solutions

Expert Solution

Solution-

For testing the given claim population standard deviations are unknown so, t test is used.

alpha is not given but generally in hypothesis testing value of alpha is 0.05.

hence, critical value at 0.05 and df = 53

t0 = ± 2.006

◆ Test calculation and results-

Test results that the null hypothesis Ho is rejected.

therefore, there is Not enough evidence to support the claim

You wish to test the following claim (H1H1) at a significance level of α=0.001α=0.001.       Ho:μ1=μ2Ho:μ1=μ2       H1:μ1≠μ2H1:μ1≠μ2 You believe both populations are normally distributed, but you do not know the standard deviations for either. However, you also have no reason to believe the variances of the two populations are not equal. You obtain a sample of size n1=24n1=24 with a mean of M1=85.8M1=85.8 and a standard deviation of SD1=19.3SD1=19.3 from the first population. You obtain a sample of size n2=17n2=17 with...
