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 the distribution of these incubation period values is left-skewed in the population of persons with HIV. If you were take a single random sample of 75 persons from this population, what will likely be the shape of the distribution of sample values? O a. right skewed O b. left skewed O c. unifornm O d. normal O e. there is no way to predict the shape of the values in the sample infected individuals is given below (in years): 12.0 10.5 13.5 12.5 9.5 6.3 7.2 Suppose the distribution of these incubation period values is left-skewed in the population of persons with HIV. If you were take a single random sample of 200 persons from this population, what will likely be the shape of the distribution of sample values? O a.right skewed O b. left skewed O c.uniform O d. normal O e. there is no way to predict the shape of the values in the sampleExplanation / Answer
When sample size greater than 30 then we consider that this sample follow normal distribution,here in both example sample size is greater than 30 so answer of both questions is normal.
