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:

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.

Step-by-step 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

Alternative hypothesis

The degree of freedom df = n -1

df = 300 - 1

df = 299

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
