Suppose that a hypothesis test is carried out such that

H_0: population mean=15 {versus} H_a: population mean ≠ 15

for a significance level of 0.10. If the probability of P (T ≥ t0) =0.025. What conclusion can we draw?

Answer #1

Conclusion finding. Here P value less than α( level of significance) so, we reject null hypothesis and population mean different from15 is TRUE.
