Question

3. The following data was collected from a simple random sample from a process (an infinite population). 13 15 14 16 12 a. The point estimate of the population mean (1 point) a. is 5 b. is 14 c. is 4 d. cannot be determined because the population is infinite

Answer 1

14

Explanation:

Given the data:

13 15 14 16 12

The point estimate of the population mean will be :

ΣX/ n

X = Given data points

N = sample size

ΣX = (13 + 15 + 14 + 16 + 12) = 70

N = 5

Hence,

ΣX/ N = 70 / 5

Point estimate of population mean = 14
