TASKS: A. Identify the appropriate method of sampling in the given situation and explain how you are going to do it. B. Create a probability distribution that includes the list of your possible samples. C. Compute for the mean, variance, and standard deviation of the sampling distribution of the means. D. Construct a probability histogram of your sampling distribution.

The purpose and intent of the assignment is to help you better understand the sampling distribution of the mean. The class sampling exercise In class we conducted a sampling exercise. The population consisted of 25 elements. The possible values for the elements in the population ranged from 1 to 9 and were distributed as follows:   Value Frequency Proportion Percentage 1               1             0.04             4% 2               2             0.08             8% 3               3             0.12            12% 4               4             0.16            16% 5               5             0.2               20% 6               4             0.16             16% 7               3             0.12             12% 8               2             0.08               8% 9               1             0.04               4%   As in the class exercise, 10 elements are drawn replacing each element before the next is drawn. This was done 1000 times.  The data set is given in a separate…

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…

Determine whether the sampling is dependent or independent. Indicate whether the response variable is qualitative or quantitative.A psychologist wants to measure the effect of music on memory. He randomly selects 80 students and measures their scores on a memory test conducted in silence. The next day he measures their scores on a similar test conducted while classical music is playing. The mean score without music is compared to the mean score with music. Group of answer choices   a.quantitative, dependent b.qualitative, independent c.qualitative, dependent d.quantitative, independent
