D and E 3. One of the ways society is trying to bring the pandemic under control is by vaccinatingpeople against the virus. The graph below shows the number of people vaccinated in SouthAfrica per day from the end of April to early in June. It is clear that the number of peoplebeing vaccinated per day has increased significantly over the past two months.021May 12, 2021Jur(Downloaded from https://www.statista.com/statistics/1231031/daily-mumber-of-covid-19-vaccination-doses-in-south-africa/ on 16.06.2021.]On 1 May 2021, 3,000 people were vaccinated and on 31 May 2021, 45,000 people werevaccinated.(a) Setting t = 0 on 1 May and t = 30 on 31 May, you want to find a function whosegraph looks similar to the shape above and has the same values of 3,000 at t = 0 and45,000 at t = 30. In each of (i) to (iv) below solve for the constants a and b so thatthe given function goes through the above points at t = 0 and t = 30.i. f(1) = at? + bii. 9(t) = ae"iii. h(t) = a + bcos (t)40iv. j(t) :a1+ be-1/10(b) For each of the four functions from (i) to (iv) in (a) caleulate the value of the derivativewhen t = 30. (Use the values for a and b that you caleulated in (a).)(c) Based on your answers in (b), if you were the new Minister of Health, which functionwould you like to see as the function describing the number of people vaccinated perday? Explain.(d) Using the graph given above, draw a rough sketch showing the total number of peoplevaccinated since 1 May 2021 against time. Draw it on the same domain as the graphabove and explain clearly the reasons for the slope and concavity of your graph.(e) Your friend says that she expects that if you carry on beyond June 2021, the graphof the total number of people vaccinated since 1 May 2021 will change concavity atsome point in the future. Do you agree with her or not? Explain.(f) Only one of the functions (i) to (iv) above will give a graph of the total number ofpeople vaccinated from 1 May 2021 to 1 May 2022 that changes concavity. Whichfunction is that? Explain.30, 2021May 4, 2021May 8, 2021May 16, 2021May 20, 2021May 24, 2021May 28, 2021Jun 1, 2021Jun 5, 2021Jun 9,

Over the past 40 years, the percentage of homes in the United States with smoke detectors has risen steadily and has plateaued at about 96% as of 2015.† With this increase in the use of home smoke detectors, what has happened to the death rate from home fires? Suppose the following contains 17 years of data on the estimated percentage of homes with smoke detectors and the estimated home fire deaths per million of population.

A company studied the number of lost-time accidents occurring at its Brownsville, Texas, plant. Historical records show that 6% of the employees suffered lost-time accidents last year. Management believes that a special safety program will reduce such accidents to 4% during the current year. In addition, it estimates that 15% of employees who had lost-time accidents last year will experience a lost-time accident during the current year. a. What percentage of the employees will experience lost-time accidents in both years (to 2 decimals)? % b. What percentage of the employees will suffer at least one lost-time accident over the two-year period (to 2 decimals)?
Suppose, a small town has 15000 people. Among the inhabitants, a pair is recently affected by a contagious disease. An affected pair can not transmit the disease until the pair is suffering for two days. After two days of sufferings, the pair can transmit the disease to another pair in each subsequent day. So, what percentage of the population will be affected after 22 days? Consider counting the number of affected people from day 1. Explain each step thoroughly, as your grade in this question will largely depend on the details of your explanation.
Suppose Laura, a facilities manager at a health and wellness company, wants to estimate the difference in the average amount of time that men and women spend at the company's fitness centers each week. Laura randomly selects 15 adult male fitness center members from the membership database and then selects 15 adult female members from the database. Laura gathers data from the past month containing logged time at the fitness center for these members. She plans to use the data to estimate the difference in the time men and women spend per week at the fitness center. The sample statistics are summarized in the table.

Suppose that we identify 155 women 50 to 54 years of age who have both a mother and a sister with a history of breast cancer. 18 of these women themselves have developed breast cancer at some time in their lives. If we assume that the proportion of breast cancer cases in women whose mothers have had breast cancer is 8%, does having a sister with the disease increase the risk? Find the p-value.

In February 2021, the Chicago Tribune reported:“The overdose epidemic that has ravaged Chicago has not spared the nearby suburbs, some of which have death rates comparable to anything seen in the city, according to a report released this week by the Cook County Department of Public Health. ZIP codes in the towns of Worth, Broadview, Maywood, and Forest Park, areas that “have substantially lower median household incomes and higher poverty rates,” have been especially hard-hit, the report said.”In the article, they claimed that lower incomes were associated with higher overdose death rates and that overdose death rates are increasing over time. The data you have been analyzing wasn’t focused on Chicago, obviously. But do your results support the general gist of the statistical argument being made in this Tribune excerpt? Please address:• Do overdose death rates appear to be associated with per capita income (use scatterplot)?• Do overdose death rates appear to be increasing over time…
