Use technology to help you test the claim about the population mean, mu, at the given level of significance, alpha, using the given sample statistics. Assume the population is normally distributed.

Claim: mu>1270; alpha=0.03; sigma=208.29. Sample statistics: x overbar=1291.42, n=250

1)PICK A CHOICE

A) H0: mu>/=1291.42 HA: mu<1291.42 B)H0:mu>12.91.42, HA mu1270, HA mu1291.42

E) HO: mu 1270 F) HO MU: >/=1270 HA:MU <1270

2)Calculate the standardized test statistic

The standardized test statistic is ???

3)Determine the P-value. ???

4)Determine the outcome and conclusion of the test.

FAIL TO REJECT/REJECT? H 0. At the 3% significance level, there IS/IS NOTenough evidence to SUPPORT/REJECT the claim
