Calculate the incidence rate of prostate cancer in this population A population of 200 healthy men was followed up for the development of prostate cancer. 10 men were followed-up for 1 year and were then lost to follow-up. After being followed-up for 5 years, 10 men developed prostate cancer. The remaining men who never developed prostate cancer were followed for 10 years.

Fertility Rates. From the U.S. Census Bureau, in the document International Data Base, we obtained data on the total fertility rates for women in various countries. Those data are presented on the WeissStats site. The total fertility rate gives the average number of children that would be born if all women in a given country lived to the end of their childbearing years and, at each year of age, they experienced the birth rates occurring in the specified year. Use the technology of your choice to decide whether total fertility rates for countries appear to be approximately normally distributed. Explain your answer.
A health officer is trying to study the malaria situation of Zambia. From the records of seasonal blood survey (SBS) results he came to understand that the proportion of people having malaria in Zambia was 3.8% in 2015. The size of the sample considered was 15,000. He also realized that during the year that followed (2016), blood samples were taken from 10,000 randomly selected persons. The result of the 2016 seasonal blood survey showed that 200 persons were positive for malaria. Help the Health officer in testing the hypothesis that the malaria situation of 2016 did not show any significant difference from that of 2015 (take the 5% level of significance).

A country club wants to exam the effects of a new marketing campaign that attempts to get more people within the community to become members. In many communities, when people buy a house in the area, they receive a “Welcome Wagon” gift basket containing coupons to local restaurants. The idea of the marketing campaign is to include a free two month membership to the country club in the gift basket with the hope that once “new” residents try the country club then at least a certain proportion will want to become real members. One member of the Club’s Executive Council believes that at least 79% of the people who receive the coupons for the free membership will use the coupon. In a sample of 204 new residents who received the coupon for the two month free membership, there were 144 people who actually took advantage of the free two month membership. When testing the hypothesis that at least 79% of the people that receive the coupon actually use it, what is the test statistic? (please…

Suppose a researcher conducts an experiment to assess the measuring capabilities of a new device aimed at detecting the boiling point of a chemical. The chemical has a known boiling point of 120 degrees Fahrenheit. His measurement device is tested 10 times, and results in the following measurements for boiling point. What can we say about the device with regards to its precision, accuracy, and potential bias?

Murder was committed in an air-conditioned laboratory. Dr. Quincy, the medical examiner, was summoned to the scene of the crime. One of the first things he did was to take the temperature of the corpse. At 9:23 PM, he recorded the temperature to be 20.1oC and at 9:53 Pm to be 18.7oC. He further observed that the thermostat of the air-conditioning unit was set at 16oC. After gathering all pertinent data and analyzing them for sometime, he submitted a preliminary report stating that the victim was murdered between 7 PM and 8 PM. Was Dr. Quincy's report correct? At what approximate time did the victim die? Assume that the normal body temperature of a human being, alive and well, is 37oC.
1.Carbon dioxide is known to have a critical effect on microbiological growth. Small amounts of CO2 stimulate growth of some organisms, whereas high concentrations inhibit the growth of most. The latter effect is used commercially when perishable food products are stored. A study is conducted to investigate the effect of CO2 on the growth rate of pseudomonas fragi, a food-spoiling organism. Carbon dioxide is administered at five predetermined different atmospheric pressures. The response measured was the percentage change in cell mass after 1-hour growing time. Ten cultures were used at each atmospheric pressure level, resulting in the following data: 0.0 .083 .29 .50 .86 62.6 50.9 45.5 29.5 24.9 59.6 44.3 41.1 22.8 17.2 64.5 47.5 29.8 19.2 7.8 59.3 49.5 38.3 20.6 10.5 58.6 48.5 40.2 29.2 17.8 64.6 50.4 38.5 24.1 22.1 50.9 35.2 30.2 22.6 22.6 56.2 49.9 27.0 32.7 16.8 52.3…
Hydraulic fracturing, or “fracking”, is the process of drilling below the surface of the earth and injecting liquid at high pressure into rock formations to extract oil and natural gas. As more states have approved fracking, an increasing number of U.S. adults have expressed concerns about its safety. A 2016 Gallup survey asked U.S. adults, “Do you favor or oppose hydraulic fracturing, or fracking, as a means of increasing the production of natural gas and oil in the U.S.?” The survey results are shown below. Support 36% Oppose 51% No Opinion 13% Which of the following scenarios would be the best use of a chi-square goodness-of-fit test? a. Researchers want to determine the proportions of all U.S. adults who support, oppose, or have no opinion about the increase of fracking in the U.S.b. Researchers want to determine if U.S. adults’ views towards fracking in 2018 are different than U.S. adults’ views towards fracking were in 2016.c. Researchers want to determine if the proportion of…
