Question

The owner of a local nightclub has recently surveyed a random sample of n = 300 customers of the club. She would now like to determine whether or not the mean age of her customers is over 35. If so, she plans to alter the entertainment to appeal to an older crowd. If not, no entertainment changes will be made. The appropriate hypotheses to test are:

Answer 1

We cannot determine the appropriate hypotheses to test this study because we are only given the data for the sample size and the population mean. Meanwhile, we need to know the data of the sample mean, the standard deviation and the level of significance before we can state the appropriate hypotheses for this test.

Explanation:

Given that:

sample size n = 300

population mean μ = 35

The null hypothesis and the alternative hypothesis can be computed as follows:

Null hypothesis

`H_o: \leq 35`

Alternative hypothesis

`H_1 > 35`

The degree of freedom df = n -1

df = 300 - 1

df = 299
