Question

Use a​ t-test to test the claim about the population mean μ at the given level of significance α using the given sample statistics. Assume the population is normally distributed.

​Claim: μ=51,300; α=0.10 Sample​ statistics:

x overbar =52,024​

s=2,100

n=19

Answer 1

Here using ti-83 calculator.

Test Hypothesis :-

H0:

Ha:

Test statistic :-

t =1.503

P-value = 0.1502

Conclusion :-

P-value is greater than alpha =0.10 then conclude that do not reject the null hypothesis (H0).

Therefore, there is not enough evidence to support the claim.
