The following data are from a simple random sample: 3, 6, 8, 15, 5, 11. What is the point estimate of the population mean?

Consider the following hypothesis test,

$H_0: \mu = 15$

$H_a: \mu ≠ 15$

A sample of 50 provided a sample mean of 14.15. If the sample standard deviation is 3, then the value of the test statistic t0-test is

As per the concept of inferential statistics, population stands for:-
