Consider the following hypothesis test. h0: μ = 15 ha: μ ≠ 15 a sample of 50 provided a sample mean of 14.11. the population standard deviation is 3. find the value of the test statistic. (round your answer to two decimal places.)

-2.10

Step-by-step explanation:

Given :

Sample size : n= 50, since the sample size is greater than 30 , so we apply z-test.

Sample mean :

Standard deviation :

The test statistic for population mean :-

i.e.

Hence, the value of the test statistic = -2.10

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.
