Question 1 - Normal Probability Distribution - By Hand

Suppose you are told that SBP (systolic blood pressure) of a group of people follow a normal probability distribution with a mean of 120 and standard deviation of 11.

a. What is the probability that a randomly selected person will have an SBP value of105 or greater?

b. What percentage of people will have an SBP value between 105 and 130?

Question 2 - Normal Probability Distribution - Solver

Using the same distribution above about SBP (systolic blood pressure). Once again assume that you have a normal probability distribution with a mean of 120 and standard deviation of 11. Take a screen snip of the solver results and post this along with your written solution.

a. What is the probability that a randomly selected person will have a SBP value of96.5 to 139.8?

b. What is the probability that a randomly selected person will have a SBP value of135 or greater?

c.What is the SBP that will give the top 10% of SBP values in this population? Round the value to 1 decimal place.

d.Bonus - Provide the lower and upper SBP values that would be considered outliers based on the rule for 3 SD's from the mean.Are these values biologically plausible?Explain.
