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 0.2. A sample of 37 U.S. adults is chosen. Use the TI-84 Plus Calculator as needed. Round the answer to at least four decimal places. ## Problem Set on Probability and Normal Approximation### Part 1 of 5**Question:**Is it appropriate to use the normal approximation to find the probability that more than 48% of the people in the sample have high blood pressure?**Answer:**It is **not** appropriate to use the normal curve, since \( np = 7.4 \) is **less than** 10, and \( n(1-p) = 29.6 \) is **greater than or equal to** 10. ### Part 2 of 5**Question:**A new sample of 82 adults is drawn. Find the probability that more than 32% of the people in this sample have high blood pressure.**Answer:**The probability that more than 32% of the people in this sample have high blood pressure is **0.0033**.### Part 3 of 5**Question:**Find the probability that the proportion of individuals in the sample of 82 who have high blood pressure is between 0.26 and 0.33.**Answer:**The probability that the proportion of individuals in the sample of 82 who have high blood pressure is between 0.26 and 0.33 is **0.0856**. **Part 4 of 5**Find the probability that less than 27% of the people in the sample of 82 have high blood pressure.The probability that less than 27% of the people in the sample of 82 have high blood pressure is 0.9441.

Determine whether the given value is a statistic or a parameter. A homeowner measured the voltage supplied to his home on 23 days of a given month, and the average (mean) value is 143.1 volts. Part 1 Choose the correct answer below. A. The given value is a statistic for the month because the data collected represent a population. B. The given value is a parameter for the month because the data collected represent a sample. C. The given value is a parameter for the month because the data collected represent a population. D.

INSTRUCTION: Perform an appropriate statistical test using the dataset (Sheet name: Raw Data) if a researcher would like to determine if there is a significant difference in the "Systolic blood pressure (SBP) "between "Male" and "Female"? Dataset for this can be retrieved on the given Excel. 1. What is the computed p-value for the given data on the SBP between Male and Female? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the Systolic blood pressure (SBP) between Male and Female? 2. What is the computed Mean of Male on the given data for Systolic blood pressure (SBP)? Round it off to two decimal places. 3. What is the computed Standard Deviation of Female on the given data for Systolic blood pressure (SBP)? Round it off to two decimal places.
