Problem 1 The National Health and Nutrition Survey reported that 30% of adults in the United States have hypertension (high blood pressure). A sample of 25 adults is studied. a) Use Excel to construct a probability distribution table for this situation. If necessary, round probability values in your table to 6 decimal places. b) Use your probability distribution table to answer the following questions. "Be sure to highlight the indicated values in your table. i. ii. iii. What is the probability that exactly 6 of the sampled adults have hypertension? "Highlight in yellow the one value in your probability distribution table that answers this question. What is the probability that fewer than 4 of the sampled adults have hypertension? Highlight in green the values in your probability distribution table that may be used to answer this question. Then, use an Excel formula to the right of your table to find the answer to this probability question, rounded to 4 decimal places. I What is the probability that more than 8 of the sampled adults have hypertension? "Highlight in blue the values in your probability distribution table that may be used to answer this question. Then, use an Excel formula to the right of your table to find the answer to this probability question, rounded to 4 decimal places. c) Find the expected number of adults in the sample who have hypertension. In other words, find the mean. *Type your answer to the right of your table on the Excel worksheet and do not round the result.
