9.

Suppose another random sample of 100 persons is taken from the same population, and added to the sample of 7, for a total sample of 107 HIV infected individuals. How will the sample standard deviation of the 107 values compare in value to the sample standard deviation from the original sample of n=7?

a. it will be larger

b. it will be smaller

c. it will be exactly the same value

d. While the two values should be "similar", there is no way to predict exactly how the two values will compare

A random sample of size n1 = 25, taken from a normal population with a standard deviation σ1 = 5.2, has a sample mean = 85. A second random sample of size n2 = 36, taken from a different normal population with a standard deviation σ2 = 3.4, has a sample mean = 83. Test the claim that both means are equal at a 5% significance level. Find P-value.
