StylesPART 2Suppose that 800 students were selected at random from a student body of 20,000 and given shots to prevent a certaintype of flu. All 800 students were exposed to the flu, and 600 of them did not get the flu. Let p represent the probabilitythat the shot will be successful for any single student selected at random from the entire population of 20,000. Let q be theprobability that the shot is not successful.(a) What is the number of trials n?(b) What is the number of successes x?(c) What is the point estimates for p and q?(d) Would it seem that the number of trials is large enough to justify a normal approximation to the binomial?(e) Compute the margin of error, E for a 99% confidence interval for p(f) Compute a 99% confidence interval for p.(o What does the confidence interval you just computed mean in the context of this application?Accessibility: Good to go

An Insurance company study shows that 70% of the auto insurance claims submitted for property damage were submitted by males user 25 years of age. Suppose 6 property damage claims involving automobiles are selected at random. Let X be the number of claims (among 6 the selected) that are made by males under age 25. Question 1 Find the probability that all 6 claims are made by males under age 25.
Suppose that the genders of the three children of a certain family are soon to be revealed. Outcomes are thus triples of “girls” (g) and “boys” (b), which we write gbg, bbb, etc. For each outcome, let R be the random variable counting the number of girls in each outcome. For example, if the outcome is bbb, then R(bbb)=0. Suppose that the random variable X is defined in terms of R as follows: X=R^2-2R-1. The values of X are given in the table below.

Based on a survey, assume that 33% of consumers are comfortable having drones deliver their purchases. Suppose we want to find the probability that when six consumers are randomly selected, exactly three of them are comfortable with the drones. What is wrong with using the multiplication rule to find the probability of getting three consumers comfortable with drones followed by three consumers not comfortable, as in this calculation: (0.33)(0.33)(0.33)(0.67)(0.67)(0.67) = 0.0108? Choose the correct answer below. A. The event that a consumer is comfortable with drones is not mutually exclusive with the event that a consumer is not comfortable with drones. B. The probability of the second consumer being comfortable with drones cannot be treated as being independent of the probability of the first consumer being comfortable with drones. O C. There are other arrangements consisting of three consumers who are comfortable and three who are not. The probabilities corresponding to those other…
