answer correctly

Exercise 11: Read and answerthe following questions 1. A random sample of 16 students is chosen from a large population with an average diastolic blood pressure of 126 and a standard deviation of 6? What is the probability that the mean diastolic blood pressure if these 16 students is less than 122? 2. Suppose that the systolic blood pressures of a certain population are normally distributed with mean a = 125 and a = 8 and a sample with size 36 is taken from this population . What is the probability that a single sample will have a mean blood pressure of less than 122? 3. Suppose that the systolic blood pressures of a certain population are normally distributed with mean j = 128 and a = 8 and a sample with size 4 is taken from this population . What is the probability that a single sample will have a mean blood pressure of less than 123
