Answer #1

Solution:

When testing the means of independent samples, the null hypothesis is best thought of as

Answer : a. the mean of a population 1 is equal to the mean of population 2

Option a is correct

i.e. H0:  1 =  2

{ Valid signs in H0 are = , and

Valid signs in H1 are , < and >

}

We are going to study the difference in means of two independent samples. We assume the difference in mean between these two samples 6.0 (assuming: mu1=16 and mu2=10), and the standard deviation (among all patients in two groups) is 10. Our hypothesis is H0: mu1 = mu2 vs Ha: mu1 not equal to mu2. To achieve a power of 80% to test the difference of 6.0, how many patients in total should we recruit? The significance level is 0.05, and...
