4. To reduce the paperwork and administrative cost, a company wants to know whether
employees are satisfied with the new reimbursement policy for meals during business
travel. In an annual survey last year, 65% of all employees reported that they were
satisfied with the old policy. To evaluate the new policy, the company conducts a new
survey of 254 employees, and finds that 160 of them support it. Is the new policy even
less popular than the old one? Use a = 0.01.

The Majoring in Money study by Sallie Mae from December 2015 showed that most college students manage their credit cards in a reasonable way. It showed that almost two-thirds of students pay their credit card balance in full every month and 25% of students who own credit cards make partial payments that exceed the minimum amount due. You are curious to find out if credit card payment behavior of students has changed since 2015 and collect data from a random sample of 370 students. You find that 71 students are making partial payments on their credit cards that exceed the minimum amount due. Using α=0.01, complete parts a and b below.
According to Padgett Business Services, 20% of all small-business owners say the most important advice for starting a business is to prepare for long hours and hard work. Twenty-five percent say the most important advice is to have good financing ready. Nineteen percent say having a good plan is the most important advice; 18% say studying the industry is the most important advice; and 18% list other advice. Suppose 14 small business owners are contacted, and assume that the percentages hold for all small-business owners.a. What is the probability that none of the owners would say preparing for long hours and hard work is the most important advice?b. What is the probability that six or more owners would say preparing for long hours and hard work is the most important advice?c. What is the probability that exactly five owners would say having good financing ready is the most important advice?d. What is the expected number of owners who would say having a good plan is the most important…
According to the IRS, individuals filing federal income tax returns prior to March 31 received an average refund of $1056 in 2018. Consider the population of “last-minute” filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15). A researcher suggests that a reason individuals wait until the last five days is that on average these individuals receive lower refunds than do early filers. For a sample of 400 individuals who filed a tax return between April 10 and 15, the sample mean refund was $910. Based on prior experience, a population standard deviation of σ = $1,600 may be assumed. Test the researcher's assertion using the critical value approach. Use α = 0.05 (Please include all the 7 steps in hypothesis testing) Steps in hypothesis testing p-value Approach Develop the null and alternative hypothesis Specify the level of significance, α Choose the test statistic (z or t) Calculate the test statistic Use the value of the…
Three businesswomen are trying to convene in Cincinnati for a business meeting. The first women (Woman 1) is arriving on a flight from Atlanta, the second (Woman 2) is arriving on a flight from Dallas, and the third (Woman 3) is arriving on a flight from Chicago. Historical data suggests that the Atlanta flight is “on time” 90% of the time, the Dallas flight is “on time” 95% of the time, and the Chicago flight is “on time” 80% of the time. Furthermore, historical data suggests that the three flights are independent with respect to on time behavior. Define the sample space for this random experiment. Compute the probability for each of the outcomes in the sample space. Let W denote the number of business women that arrive on time. Construct the probability mass function of W Construct the cumulative distribution function of W Find the expected value of W Compute the standard deviation of W

Politifact reported that on September 29, 2015, Cecile Richards, then president of Planned Parenthood, was testifying before Congress. Rep. Jason Chaffetz (R, Utah) accused Ms. Richards of misusing the $500 million in annual funding that her organization receives from the federal government. Congressman Chaffetz presented the following chart from Americans for Life. He explained, “In pink, that’s the reduction in the breast exams, and the red is the increase in the abortions. That’s what’s going on in your organization?” Here is the chart: PlannedParenthood.png Does this chart present an honest representation of the data, or is it misleading? Explain your answer. If this chart misleading, are the congressman and the Americans United for Life (the creators of the chart) knaves or fools?
It is costly in both time and money to go to college. Does it pay off? According to the Bureau of the Census, the answer is yes. The average annual income (in thousands of dollars) of a household headed by a person with the stated education level is as follows: 24.8 if ninth grade is the highest level achieved, 41.2 for high school graduates, 59.3 for those holding associate degrees, 82.6 for those with bachelor's degrees, 100.3 for those with master's degrees, and 121.7 for those with doctoral degrees. Make a bar graph showing household income for each education level.

Suppose you took a survey designed to assess criminal justice students and their attitudes towards ending cash bail in California. You ask 100 students (randomly sampled) how much they'd be willing to pay to fund community supervision programs over the current cash bail system. There is another question that asks students if they believe reforming cash bail is a serious issue. Select all correct answers. The response variable is a student's belief that cash bail needs to be reformed. The reponse variable is the amount of tax a student is willing to pay to cover community supervision costs. Students answer yes or no to the question of whether they believe cash bail reform should occur. This means the samples are independent. Students answer yes or no to the question of whether they believe cash bail reform should occur. This means the samples are dependent.
