Approximately 8.26% of patients in the Seasonal Effect data set contracted an SSI. If this happens completely randomly, calculate the probability that three randomly selected patients all contract an SSI in each of the following two ways: Using counting rules and probability trees (10%) Using the binomial distribution (hint: n=3, p=0.0826) (10%) 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,...

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%)...

Stomach pH values fluctuate between 1.5 and 3.5. The researchers expect that in healthy patients in their study, this will also be the case, and that approximately 50% of the healthy patients will have a stomach pH below 2.5. After collecting data, they find that 30 of 87 healthy patients, or 34.48%, have stomach pH levels below 2.5. Use this information to answer 1. Assume that the probability that a healthy patient has a stomach pH below 2.5 is 50%....

If you were looking at the healthy fitness rate on patients and your current rate was 92% and this was out of the last 1550 patients that you deal with. If you wanted your rate to increase to 96% for the next 1550, how many more would you have to put into the list? What would be the step by step process?

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. 4. Use the Central Limit Theorem to calculate the standard error of the sample mean of the sample of 241 patients. Show your work. (5%) Please explain the steps as well so I understand.

Please use Rstudio to answer the following question. Thank you. In a double-blind experiment, healthy volunteers agreed to be exposed to a cold virus. They were either assigned to a control group (no echinacea but a placebo) or the group with echinacea. Here are the results Placebo group: 103 subjects 88 got a cold Echinacea group: 48 subjects 44 got a cold. a. Calculate the proportions getting cold in each group. b. Use a two-sample test to compare the proportions....
