Question

Only answer please its super easier for you no explanation required

Oe The duration of time from first exposure to HIV infection to AIDS diagnosis is called the incubation period. The incubation
periods of a random sample of 7 HIV infected individuals is given below (in years):
12.0
10.5
13.5 12.5. 9.5
6.3
7.2
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 mean of 107 values compare in value to
the sample mean from the original sample of n=7?
It will be exactly the same value
It will be larger
It will be smaller
While the two values should be "similar", there is no way to predict exactly how the two values will compare
