The duration of time from first exposure to HIV infection to AIDS diagnosis is c

Question

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? O a. it will be larger O b. It will be smaller O 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 The duration of time from first exposure to HIV infection to AIDS diagnosis is called the incubation period.

Explanation / Answer

Yes the correct option is d. Because the samples are taken from the same population so similar values in the means should be given. But we can not predict the exact comparison between two means as the data set for 100 samples is not given.
