1. Choose an appropriate procedure. For each of the following questions, indicate whether you would use ahypothesis test or a confidence interval to answer it. Then state hypotheses if you would use a hypothesistest, or indicate the parameter(s) using correct notation if you would use a confidence interval. You do notneed to carry out any procedures or define the parameters.a. In what proportion of all grocery store trips is whole milk is purchased? You would use a (check one):Hypothesis test with hypotheses:Confidence interval for the parameter(s) - notation only:b. Is average fuel mileage for a Honda Civic different from the EPA stated value of 34 MPG? You woulduse a (check one):Hypothesis test with hypotheses:Confidence interval for the parameter(s)- notation only:c. On average, how much more weight is lost on a new trial drug than on a placebo? You would use a(check one):Hypothesis test with hypotheses:Confidence interval for the parameter(s)-notation only:

The hypothesis is an assumption that is being tested.

For the following hypotheses, identify the independent and dependent variables. States with more restrictions on obtaining abortions will have lower abortion rates. Counties paying teachers more will have higher standardized test scores. The lower a state’s per capita income, the less money spent per resident on road maintenance.
Read the following problem description then choose the correct null and alternative hypothesis. A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO is less than 1 in every one thousand.
Solve the following problems. Use the steps in conducting hypothesis tests.We are interested in whether the proportions of female suicide victims for ages 15 to 24 are the same for the whites and the blacks races in the United States. We randomly pick one year, 1992, to compare the races. The number of suicides estimated in the United States in 1992 for white females is 4,930. Five hundred eighty were aged 15 to 24. The estimate for black females is 330. Forty were aged 15 to 24. We will let female suicide victims be our population.
Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
Test the following claims. This process should include each step as outlinedin the text In Mendel’s pea experiments, 6,022 yellow peas were observed out of a sample of8,023 peas. Test the claim, at 1% significance, that the proportion of these peas thatwere yellow is equal to 75%, against the alternative that the proportion is not 75%
