Test the claim about the population mean μ at the level of significance α $\alpha$ Assume the population is normally distributed. Claim: $\mu = 1400 ; \alpha = 0.01 ; \sigma = 82$
Sample statistics: $\bar { x } = 1370 , n = 35$
A)Fail to reject $\mathrm { H } _ { 0 }$ There is enough evidence at the 1% level of significance to support the claim.
B)Reject $\mathrm { H } _ { 0 }$ . There is enough evidence at the 1% level of significance to reject the claim.
C)Not enough information to decide.
