1. The systolic blood pressure (given in millimeters) of females has an approximately normal distribution with mean μ = 122 millimeters and standard deviation σ = 16 millimeters. Systolic blood pressure for females follows a normal distribution. What is the probability that a female’s systolic blood pressure is less than 90 millimeters? Round answer to 3 decimal places
2. The systolic blood pressure (given in millimeters) of females has an approximately normal distribution with mean μ = 122 millimeters and standard deviation σ = 16 millimeters. Systolic blood pressure for females follows a normal distribution. What is the probability of a patient having a blood pressure of exactly 120 millimeters?
3. The systolic blood pressure (given in millimeters) of females has an approximately normal distribution with mean μ = 122 millimeters and standard deviation σ = 16 millimeters. Systolic blood pressure for females follows a normal distribution. 5% of patients will have a blood pressure LESS than what value? Round answer to two decimal places
4. The systolic blood pressure (given in millimeters) of females has an approximately normal distribution with mean μ = 122 millimeters and standard deviation σ = 16 millimeters. Systolic blood pressure for females follows a normal distribution. 10% of patients will have blood pressure MORE than what value? Round answer to two decimal places
5. The systolic blood pressure (given in millimeters) of females has an approximately normal distribution with mean μ = 122 millimeters and standard deviation σ = 16 millimeters. Systolic blood pressure for females follows a normal distribution. Find the 25th percentile. Round answer to two decimal places
