Question

I just need the graphs and charts.

TASK 1: Describe the distribution of the population of 1,000 people. Include a histogram and the five-number summary. Follow the instructions in the end of the chapter appendix on Excel to generate the samples. Specifically, in Excel you can use Tools > Data Analysis > Sampling to generate SRS samples.
TASK 2:  Samples and sampling distributions. Choose an SRS of 30 members from this population. Make a histogram of the 30 incomes in the sample and find the five-number summary. Then repeat the process of choosing an SRS of size 30 four more times (five in all).

TASK 3A: Do the medians and quartiles of the sample provide reasonable estimates of the population median and quartiles?

TASK 3B. Use your software to produce an additional 25 (a total of 30 with the 5 from TASK 2 – SRSs of size 30 from this population. Find the mean income for each sample and save these 30 sample means in a new column. Make a histogram of the distribution of the 30 sample means.
