Bob Feller, an Iowa farmer, has recorded the daily high temperatures during the same five-day stretch in May over the past five years. Bob is interested in whether this data suggeststhat the daily high temperature obeys a normal distribution. Use α = 0.01 and conduct agoodness of fit test using 5 classes to see whether the following sample appears to havebeen selected from a normal probability distribution.(Note: x53= 68.2 and s 18.)84 92 56 53 93 53 50 67 93 88 63 85 48 5453 55 96 56 77 90 60 57 86 43Find the value of the test statistic.Find the p-value.

Beef Consumption. According to Food Consumption, Prices, and Expenditures, published by the U.S. Department of Agriculture, the mean consumption of beef per person in 2011 was 57.5 lb. A sample of 40 people taken this year yielded the data, in pounds, on last year’s beef consumption given on the WeissStats site. Use the technology of your choice to do the following. a. Obtain a normal probability plot, a boxplot, a histogram, and a stem-and-leaf diagram of the data on beef consumptions. b. Decide, at the 5% significance level, whether last year’s mean beef consumption is less than the 2011 mean of 57.5 lb. Apply the onemean t-test. c. The sample data contain four potential outliers: 0, 0, 0, and 13. Remove those four observations, repeat the hypothesis test in part (b), and compare your result with that obtained in part (b). d. Assuming that the four potential outliers are not recording errors, comment on the advisability of removing them from the sample data before performing the…

34% of CSU students participate in the Statistics Games while they attend CSU. You take a random sample of 40 students. You want to determine the probability that more than 15 of them have participated in the Statistics games. Since the conditions are met, you decide to use the Normal model to find your answer. What is the mean and standard deviation of the sampling distribution?

The average income tax refund for the 2017 tax year was $1997. Assume the refund per person follows the normal probability distribution with a standard deviation of $943. Use this model to answer the following questions. Don’t use Excel formulas – use the tables. Show the standardization and other calculations. a) For a randomly selected return, what the is probability that the refund exceeds $2500 ? b) For a randomly selected return, what the is probability that the refund is between $2000 and $3000? c) What is the 3rd quartile of the refund amount? d) The 20th percentile?
