In a large clinical trial, 394,108 children were randomly assigned to two groups. The treatment group consisted of 198,537 children given a vaccine for a certain disease, and 30 of those children developed the disease. The other 195,571 children were given a placebo, and 105 of those children developed the disease. Consider the vaccine treatment group to be the first sample. Complete parts (a) through (d) below. a.

A global corporation is currently in the process of expanding its operations, and the only option is to move to another site. The Human Resource Team has conducted a survey to its employees who live far from the site in order to find out if they are willing to stay in dormitories. The survey categorizes its respondents according to gender. In the samples sample of 500 males and 800 females, those who are willing to stay in dormitories are 241 and 168, respectively. Construct a 98% confidence interval for the difference between the two population proportions. Assuming that the HR’s estimated difference between the proportion of genders who are willing to stay in dormitories is 35%, is the team’s estimation accurate?

This obstetrician also wanted to determine the impact that three experimental diets had on the birth weights of pregnant mothers. She was also interested if age had an impact on birth weights. She randomly selected 27 pregnant mothers in the first trimester of whom 9 were 20 to 29 years old, 9 were 30 to 39 years old, and 9 were 40 or older. For each age group, she randomly assigned the mothers to one of three diets. After delivery, she measured the birth weight (in grams) of the babies and obtained the data a) What is the blocking variable?

A college student is interested in whether presoaking time has an effect on cleanliness of clothing. He collects the dirty clothes from all of the people in his dorm and randomly assigns clothing to one of four presoak time conditions: 5 minutes, 10 minutes, 15 minutes, 20 minutes. He then asks members of another dorm to rate the cleanliness of the items (they don’t know which clothing got which soaking time). The data are presented below.

A certain virus affects 0.7% of the population. A test used to detect the virus in a person is positive 87% of the time if the person has the virus (true positive) and 14% of the time if the person does not have the virus (false positive). Fill out the remainder of the following table and use it to answer the two questions below based on a total sample of 100,000 people. Virus No Virus TotalPositive Test Negative Test Total 100,000a) Find the probability that a person has the virus given that they have tested positive. Round your answer to the nearest hundredth of a percent and do not include a percent sign. % b) Find the probability that a person does not have the virus given that they test negative.
