7. In an American Animal Hospital Association survey, 37% of respondents stated that they talked to their pets on the telephone. A veterinarian found this result hard to believe, so he randomly selected 150 pet owners and discovered that 54 of them spoke to their pet on the telephone. At 0.05 significant level, test the result stated by the American Animal Hospital Association.
8. With a random sample 1026 adult Americans, 534 stated the amount of federal tax they have to pay is too high. Use 0.01 significant level to test the claim that at least half of Americans say federal tax is too high.

Skitzy Schizophrenic at the American Medical Association wrote a
report recently that stated the average annual salary of
psychiatrists is $185,000 with a population standard
deviation of $27,000 (σ= 27000). A group of hospital
administrators in the Northeast randomly sampled 64 psychiatrists
(n = 64) to test to see if psychiatrists in their region have a
different average. Their sample was found to have an
average annual salary of $194,630 .
Conduct a hypothesis test to determine if the average salary at
this...

A survey conducted by the American Automobile Association showed
that a family of four spends an average of $215:60 per day while on
vacation. Suppose a sample of 64 families of four vacationing at
Niagara Falls resulted in a sample mean of $252:45 per day and a
sample standard deviation of $74:50. Using a 98% confidence
interval estimate, you wish to determine whether the average amount
a family of four will spend when vacationing at Niagara Falls per
day is...
