MULTIPLE CHOICE QUESTION

15 mins • 1 pt

Test the claim about the population mean μ at the level of significance α. Assume the population is normally distributed.


Claim μ = 25; α = 0.01. Sample statistics: x = 25.2, s = 2.6, n = 18

Reject Ho, at 1% level of significance, there is enough evidence to reject the claim.

Fail to reject Ho, at 1% level of significance, there is not enough evidence to support the claim.

Fail to reject Ho, at 1% level of significance, there is not enough evidence to reject the claim.

Reject Ho, at 1% level of significance, there is enough evidence to support the claim.
