Here is the histogram of the distribution for systolic readings of blood pressure. How many classes are here? Estimate a range of a data. Find the bin width (a width of a class). Estimate the range of a class where the median lies. Do you expect the mean to be greater or less than the median. Explain your answer. Estimate the proportion of systolic measurements below 100.

Assume that the population of diastolic measurement for blood pressure is normally distributed with a mean of 72 and a standard deviation of 12. What proportion of the population would have a diastolic measurement above 93. Draw the Normal distribution, and shade the region that correspond the proportion.

For males in a certain town, the systolic blood pressure is normally distributed with a mean of 105 and a standard deviation of 10. Using the empirical rule, determine the interval of systolic blood pressures that represent the middle 99.7% of males.

Suppose that the mean systolic blood pressure for women over age seventy is 132 mmHg (millimeters of mercury), with a standard deviation of 9 mmHg. Suppose that the blood pressures are normally distributed. Complete the following statements.(a) Approximately 68% of women over seventy have blood pressures between mmHg and mmHg.(b) Approximately of women over seventy have blood pressures between 105 mmHg and 159 mmHg.

Question 2: The National Center for Health Statistics reports that the systolic blood pressure for males 35 to 44 years of age has a mean of 128. In a study of business executives, a random sample of 100 executives has a mean systolic blood pressure of 134. Do the data suggest that the mean systolic blood pressure for business executives is higher than 128?

Which of the following is the proportion of the total area that must be to the left of the median, in a histogram?
