Claim u = 977. Sample data: n = 25 and xbar = 984, s = 25. The sample data appear to come from a normally distributed population with o = 28. Does the hypothesis test involve sampling distribution of means that is normal, student t or neither?

Answer #1

Answer :

given data :-

Claim = 977.

Sample data: n = 25

xbar = 984,

s = 25.

= 28

The sample data appear to come from a normally distributed population

Now we need to find out the hypothesis test involve sampling distribution of means that is normal, student t or neither?

The correct answer for the given statement is,

Answer : student t distribution

Explanation :

We need to utilize understudy t dispersion in light of the fact that in the given information

sigma is known and test estimate under 30.
