Blood pressure: High blood pressure has been identified as a risk factor for heart attacks and strokes. The proportion of U.S. adults with high blood pressure is 0.30. A sample of 33 U.S. adults is chosen. Use Excel as needed.(c) Find the probability that the proportion of individuals in the sample of 81 who have high blood pressure is between 0.23 and 038. Round the answer to at least four decimal places. The probability that the proportion of individuals in the sample of 81 who have high blood pressure is between 0.23 and 0.38 is l l. Part 4 of 5 (d) Determine whether to reject H. (Choose one) V the null hypothesis H. X Reject Do not rejectCollege tuition: The mean annual tuition and fees for a sample of 14 private colleges in California was $33,500 with a standard deviation of $7350, A dotplot shows that it is reasonable to assume that the population is approximately normal. Can you conclude that the mean tuition and fees for private institutions in California is less than $35,000? Use the (1 : 0.10 level of significance and the Pvalue method with the TI84 Plus calculator
