The following data represent the responses to two questions asked in a survey of 10 college students majoring in business-What is your gender? (male = M; female = F) and What is your major? (accounting = A; computer information systems = C; marketing = M). Complete parts (a) and (b). м м M A C Gender: F F M F M Major: M A A A a. Tally the data into a contingency table where the two rows represent the gender categories and the three columns represent the academic-major categories. Student Major Categories Gender A Totals Male 3 6 Female 1 2 4 Totals 4 4 10 b. Construct contingency tables based on percentages of all 10 student responses, based on row percentages and based on column percentages. Complete the following contingency table based on total percentages. Student Major Categories Gender A M Totals Male 30.00 10.00 20.00 60.00 Female 10.00 10.00 20.00 40.00 Totals 40.00 20.00 40.00 100.00 (Round to two decimal places as needed.)

From the given scenario, define the population proportion. In 2019, a national survey organization asked the question "Do you go on more than two vacations per year?" to a random sample of 2,000 Americans. 580 responded "Yes", while the other 1,420 people responded "No".   Group of answer choices:   A) the proportions of the sampled Americans who go on more than two vacations per year   B) the proportion of all Americans who go on more than two vacations per year   C) the 1,420 people who responded "No"   D) the 2,000 Americans

Twenty-nine college students, identified as having a positive attitude about Mitt Romney as compared to Barack Obama in the 2012 presidential election, were asked to rate how trustworthy the face of Mitt Romney appeared, as represented in their mental image of Mitt Romney’s face. Ratings were on a scale of 0 to 7, with 0 being “not at all trustworthy” and 7 being “extremely trustworthy.” Here are the 29 ratings:  2.6 3.2 3.7 3.3 3.4 3.6 3.7 3.8 3.9 4.1 4.2 4.9 5.7 4.2 3.9 3.2 4.5 5.0 5.0 4.6 4.6 3.9 3.9 5.3 2.8 2.6 3.0 3.3 3.7   a 95% confidence interval for the mean rating. Is there significant evidence at the 5% level that the mean rating is greater than 3.5 (a neutral rating)?

Statistics Question

California insurance companies wanted to study factors (e.g., the proximity to a major earthquake fault line) that may influence homeowners’ decisions to purchase earthquake insurance. Surveys were mailed to randomly selected households in three California counties to investigate the possible proximity effect. The data collected are shown below:                          Los Angeles        San Bernardino         Santa Clara sample size     1,000                      1,400                         1,200 Number with     377                       469                            390 earthquake insurance   Los Angeles County is located closest among the three to a major earthquake fault line. Are homeowners in Los Angeles County more likely to purchase earthquake insurance than those in San Bernardino County? Test using α = 0.05. (Optional) Are homeowners in Los Angeles County more likely to purchase earthquake insurance than those in Santa Clara County? Use α = 0.05.

According to the National Center for Education Statistics, 43% of the college students work full time. A survey of 900 randomly selected college students is to be conducted. For such groups of 900, would it be unusual to get 735 college students who work fulltime?

3) Reynoldsburg surveys their high schoolers. They found 60% of students had cheated on a test and 80% of those who cheated felt guilt about it. What percent of all high schoolers in Reynoldsburg have both cheated and felt guilty about it?

Sierra College students enrolled in an online Elementary Statistics course were asked to participate in an anonymous onlne survey. The survey asked the students "Which type of device will you primarily use to access your online course in Canvas?". Of the 152 students who answered this question, 20 responded "a desktop computer", 121 responded "a laptop computer", 6 responded "a smartphone", and 5 responded "a tablet". The Sierra College Mathematics Department believes that less than 5% of students enrolled in an online Elementary Statistics course primarily uses a smartphone to access their online course in Canvas. Use the data collected in the survey to conduct a hypothesis testing procedure to test this belief. What conclusion should be reached according to the results of this hypothesis test?
