savings banks are permitted to sell life insurance. The approval process consists of underwriting, which includes a review of the application, a medical information bureau check, possible requests for additional medical information and medical exams, and a policy compilation stage, in which the policy pages are generated and sent to the bank for delivery. The ability to deliver approved policies to customers in a timely manner is critical to the profitability of this service to the bank. Using the DCOVA framework you define the variable of interest as the total processing time in days. You collect the data by selecting a random sample of 27 approved policies during a period of one month. You organize the data collected in a worksheet and store them in

- An insurance company has the business objective of reducing the amount of time it takes to approve applications for life insurance. The approval process consists of underwriting, which includes a review of the application, a medical information check, possible requests for additional medical information and medical exams, and a policy compilation stage in which the policy pages are generated and sent for delivery. The ability to deliver approved policies to customers in a timely manner is critical to the profitability of this service.

Their past experience indicates that 20% of the new agents hired fail to produce the minimum sales in their first year and are dismissed. Their ex- pectation is that this new screening program will reduce the percentage of failed new agents to 15% or less. If that occurs, they would save $1,000,000 in recruiting and training costs each year. At the end of the first year they want to develop an evaluation to determine if the new program is successful. The following questions are an important part of their re- search design.A total of 20 new agents were selected.a. If this group performs at the same level as past groups, what is the probability 17 or more success- fully meet their minimum sales goals in the first year?b.

- You may need to use the appropriate appendix table or technology to answer this question. For many years, businesses have struggled with the rising cost of health care. But recently, the increases have slowed due to less inflation in health care prices and employees paying for a larger portion of health care benefits. A recent survey showed that 52% of employers are likely to require higher employee contributions for health care coverage this year relative to last year. Suppose the survey was based on a sample of 700 companies likely to require higher employee contributions for health care coverage this year relative to last year. At 95% confidence, compute the margin of error for the proportion of companies likely to require higher employee contributions for health care coverage. (Round your answer to four decimal places.)

- The Angla Ruston University operates a Laundromat, solely for the purpose of providing laundering services to students in residence. You have been hired as accounting students to analyze the cost of the laundering services and develop a cost function which describes the behaviour of the laundering costs. The university administration has assembled the data for a twelve-month period pertaining to the monthly total costs of providing the service and the corresponding number of students who used the laundering facilities each month. You were recently taught how to use the Excel graphing tool and a member of the team successfully generated the scattergram given below from the data set provided.

Such roads are generally built for one or two seasons of use for limited traffic and are designed with the goal of reestablishing vegetative cover on the roadway and adjacent disturbed area within ten years after the termination of the contract, permit, or lease. The timber sale contract requires out sloping, removal of culverts and ditches, and building water bars or cross ditches after the road is no longer needed. As part of this estimation process, the company needs to estimate haul costs. The USDA publishes variable costs in dollars per cubic- yard-mile of hauling dirt according to the speed with which the vehicle can drive. Speeds are mainly determined by the road width, the sight distance, the grade, the curves, and the turnouts. Thus, on a steep, narrow,…arrow_forwardABC enters into a contract to help DEF, a ramen restaurantto design a market strategy to compete with DEF. The contract spans twelve month. DEF will pay P80,000 at the beginning of each month. At the end of the contract, ABC either will give DEF a refund of P25,000 or will be entitled to an additional P15,000 bonus, depending on whether sales at DEF at year- end increased to a target level. At the inception of the contract , ABC estimates a 30% chance that it will not earn the bonus and calculates the contract price based on the expected value of future payments to be received. At the start of the fifth month, circumstances change and ABC revise the probability that it will earn the bonus to 80% What is the adjustment to the service revenue ?arrow_forward
