The average BMI of the 241 patients who contracted an SSI in the Seasonal Effect data set is approximately 27.9 with a sample standard deviation of approximately 6.53. Use this information to answer questions 4-6.

6. The researchers decide they need a more accurate estimate of BMI’s of patients contracting SSIs. If the researchers want to be able to create a 99% confidence interval for the mean BMI of patients contracting an SSI with a margin of error equal to +/- 0.5, how large should the sample be? Show your work. (Hint: see page 316. Be sure to use the correct equation) (15%)

    Approximately 8.26% of patients in the Seasonal Effect data set contracted an SSI. If this happens completely randomly, in a random selection of 10, calculate the following probabilities, from a binomial distribution with parameters n=10 and p=0.0826. Show all work. Identify the complement of {X≥1} and use the rule of complements to calculate the probability that at least 1 patient contracts an SSI, P(X≥1) (10%) probability that more than 1 but less than 5 patients contract an SSI, P(1<X<5) (10%)...
