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…

COVID has altered our world. But how many people have really died in the world? (media form here) Select an answer people! That's a really big number, but how can we understand that number? One way is to talk about the case fatality rate, that's the chance that a person who gets COVID will die. Based on the table, that is % of people who get COVID will die. That is in every 100 people or in every 1000 people. Another valuable number to consider is what percent of our total population have died? 36. That means 1 in every people have died. Submit Question

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.
