Community Bank would like to increase the number of customers who use payroll direct deposit. Management is considering a new sales campaign that will require each branch manager to call each customer who does not currently use payroll direct deposit. As an incentive to sign up for payroll direct deposit, each customer contacted will be offered free checking for two years. Because of the time and cost associated with the new campaign, management would like to focus their efforts on customers who have the highest

- The vintage Restaurant is located on Captiva Island, a resort community located near Fort Meyers, Florida. The restaurant, which is owned and operated by Karen Payne, has just completed its third year of operation. During this time, Karen sought to establish a reputation for the restaurant as a high-quality dining establishment that specializes in fresh seafood. The efforts made by Karen and her staff have proved successful, and her restaurant has become one of the best and fastest-growing restaurants on the island. Karen has just concluded that to plan better for the growth of the restaurant in the future, it is necessary to develop a system that will enable her to forecast food and beverage sales by the month for up to 1 year in advance. Karen has the following data available on the total food and beverage sales that were realized during the previous 3 years of operation.

The U.S. National Institute on Drug Abuse claims that about 15% of people in the 18-25 age bracket use illegal drugs. Allyn Clark, a 21 year-old college graduate, applied for a job at the Acton Paper Company, took a drug test, and was not offered a job. He suspected that he might have failed the drug test, even though he does not use drugs. In checking with the company's personnel department, he found that the drug test has 99% sensitivity, which means that only 1% of drug users incorrectly test negative. Also, the test has 98% specificity, meaning that only 2% of nonusers are incorrectly identified as drug users. Allyn felt relieved by these figures because he believed that they reflected a very reliable test that usually provides good results. But is this really true? The accompanying table shows data for Allyn and 1,999 other job applicants. Based…arrow_forward
- please help with 3, 4, and 5 High school seniors with strong academic records apply to the nation’s most selective colleges in greater numbers each year. Because the number of slots remains relatively stable, some colleges reject more early applicants. Suppose that for a recent admissions class, an Ivy League college received 2851 applications for early admission. Of this group, it admitted 1033 students early, rejected 854 outright, and deferred 964 to the regular admission pool for further consideration. In the past, this school has admitted 18% of the deferred early admission applicants during the regular admission process. Counting the students admitted early and the students admitted during the regular admission process, the total class size was 2375. Let E, R, and D represent the events that a student who applies for early admission is admitted early, rejected outright, or deferred to the regular admissions pool.

He estimated the price of his dream vehicle as 2.4 million rupees, but unable to purchase it so far due to the financial constraints he faced. Now due to the changes in the import policies of the new government, different people argue that prices of the vehicle have also changed. Therefore, in order to test whether the price of his dream vehicle has changed or not, he checked the prices of 18 such vehicles (in million rupees) advertised in the weekend newspaper and the sample mean was = 2.14 and standard deviation was 0.22. Test at 5% level of significance whether the price of his dream vehicle has changed?arrow_forwardTo the Internal Revenue Service (IRS), the reasonableness of total itemized deductions depends on the taxpayer's adjusted gross income.

Approximately 45% of the U.S. population has type O blood. However, type O is routinely in short supply and in high demand by hospitals—both because it is the most common blood type and because type O negative blood, in particular, is the universal blood type needed for emergency transfusions. The local American Red Cross is holding a blood drive. How many donors should they expect to collect from until they get a donor with type O blood? What is the probability that the first donor with type O blood occurs on the mean of the distribution? Round your answer to the nearest hundredth if necessary.
