Pet Ownership According to the 2018 General Social Survey (GSS), 60% of all U. S. households have at least one pet. A veterinarian in Ann Arbor decided to conduct a survey to assess if over 60% of all Ann Arbor households have at least one pet. A 10% significance level was selected to be used. The random sample of 280 Ann Arbor households resulted in 182 stating they currently have at least one pet. These results are turned over to you to perform the appropriate test.
a. State the appropriate hypotheses to be tested with a complete definition of the parameter of interest. (the significance level has been selected to be 10%).
b. Check the necessary assumption(s) (you may assume that the selected sample is a random sample).
c. Perform the appropriate test (include all supporting computations for the test statistic and p-value).
d. Give your decision and provide a conclusion in context.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
