- Previous answer was absolutely incorruA traditional performance rating benchmark (or guideline) for “normal” effort, or speed, is dealing 52 cardsinto four piles, forming a square with each pile one footapart, in 0.50 minute. Conduct an experiment with one ormore fellow students in which one deals the cards andthe others rate the dealer’s performance, and then compare these subjective ratings with the actual time of thedealer.ASAP Exercise 7-48 (Algo) (LO7-3) According to a government study among adults in the 25- to 34-year age group, the mean amount spent per year on reading and entertainment is $2,125. Assume that the distribution of the amounts spent follows the normal distribution with a standard deviation of $439. (Round your z-score computation to 2 decimal places and final answers to 2 decimal places.) a. What percent of the adults spend more than $2,400 per year on reading and entertainment? b. What percent spend between $2,400 and $3,400 per year on reading and entertainment? c. What percent spend less than $1,000 per year on reading and entertainment?

Researchers questioned 1000 individuals fromCalifornia between the ages of 20 and 85 about their eating habits, andmeasured their weight and height. On average, participants ate chocolatetwice a week and had a body mass index (BMI) of 28. There was anobserved difference of five to seven pounds in weight between those whoate chocolate five times a week and those who did not eat any chocolate atall, with the chocolate eaters weighing less on average. Frequent chocolateeaters also consumed more calories, on average, than people who consumedless chocolate. Based on this summary, would you recommend thatAmerican’s who do not presently eat chocolate, consider eating chocolateup to five times a week if they want to lose weight? Why or why not?Explain.

The fast food chain is interested in measuring the population variance in the number of customers it has on adaily basis in all its stores in the U.S. However, it is limited in its ability to track this number across all stores and has to select a sample. Think critically about thefollowing questions:1. There are two estimators for the population variance with different levels of bias and variance. Explain how you would go about choosing between thesetwo estimators.2. You are interested in coming up with a 95% confidence interval for the population variance. How would you go about deciding the number of outlets tosample?
