Suppose μ1 and μ2 are true mean, for An experiment resulted in the following data:

System 1: m = 6, Xbar= 115.7, s1= 5.03;

System 2: n = 6, Ybar=129.3, s2= 5.38.

Use the two-sample t test at significance level 0.01 to test H0: μ1- μ2= -10 versus Ha: H0: μ1- μ2 < -10. You can use either critical value or p-value to reach to a conclusion.

Please be as detailed as possible and list any assumptions made. Thank you very much!

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...
