2. The Department of Fish and Wildlife looked at the ages of individuals between 65 and 81 that frequented the Bolsa Chica Reserve during the week of June 13th, 2021, to help determine if more facilities and resources are necessary to support the needs of that age group. They determined there were 40 individual visitors that fit those criteria, with the following ages: 65, 66, 66, 67, 67, 67, 68, 68, 68, 68, 69, 69, 69, 69, 69, 69, 70, 70, 70, 70, 70, 71, 71, 71, 71, 72, 72, 72, 73, 73, 73, 74, 74, 75, 75, 76, 77, 78, 79, and 80.

Calculate the mean and standard deviation for the population. Now take 10 samples of size 3 from the population. Use either simple random sampling or systematic sampling with the help of the table of random numbers in Appendix A. Calculate the mean for each sample. Once you have calculated the mean for each sample, calculate the mean of means (i.e., add up your 10 sample means and divide by 10). How does this mean compare with the mean for all…

Subject Area % Books in Circ Library on this Subject No. of Books in the Sample on this Subject Business 32% 1210 Humanities 25% 956 Natural Science 20% 940 Social Science 15% 814 Other Subject 8% 297 Using a 5% level of significance, test the claim that the subject distribution of books in the library fits the distribution of books checked out by students.
15 Projected undernourished individuals. In 2020, The FAO, IFAD, UNICEF, WFP, and WHO published a brief .... NOURISH report on the state of food security and nutrition in the world. There were 687.8 million undernourished people in the world in 2019. One of the sections in the report shows the distribution of these people as shown in the following table: Region Africa Asia Northern America and Europe Oceania Latin America and the Caribbean Percentage of undernourished people (%) 36.4 55.4 0.9 0.4 6.9 a. Describe the variable measured in the table. b. These results were displayed in the form of a pie chart. Reconstruct the pie chart from the information given in the table. c. How many of the 687.8 million undernourished people in the world in 2019 were in Africa? d. As Africa has many third world countries, people might expect Africa to have the highest number of undernour- ished people in the world. Does the information in the pie chart, part b, support this contention? Explain why or…
