A random sample of eleven such families has a mean nightly lodging rate of $126 with a standard deviation of $12. Is there enough evidence to reject the claim at Assume the population is normally distributed.
8a) Write the null and alternative hypothesis mathematically and identify the claim :(claim):
9Find the critical values and identify the rejection region
11ConclusionDecide whether to reject or fail to reject the null hypothesis. Then interpret the decision in the context of the original claim.At the 10% level, reject the null hypothesis. Evidence does not supports the claim that the mean daily meal cost is greater than or equal to $136.
