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 0.4. 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. Part: 0 / 6 Part 1 of 6 Is it appropriate to use the normal approximation to find the probability that more than 45% of the people in the sample have high blood pressure? It is and n (1-p): Part: 1 / 6 Part 2 of 6 Part: 2/6 Part 3 of 6 Find the probability that more than 45% of the people in this sample have high blood pressure. The probability that more than 45% of the people in this sample have high blood pressure is 0.2674 Part: 3 / 6 Part 4 of 6 ▼ 10 A new sample of 83 adults is drawn. Find the probability that more than 41% of the people in this sample have high blood pressure. The probability that more than 41% of the people in this sample have high blood pressure is Part: 4 / 6 appropriate to use the normal curve, since np = 14.8 Part 5 of 6 = 22.2 > ▼10.

Part 4-6

**Blood Pressure and Probability Analysis**

**Overview:**
High blood pressure is a significant risk factor for heart attacks and strokes. In this analysis, we explore the probability of high blood pressure prevalence in various samples of U.S. adults.

**Statistics Provided:**
- Proportion of U.S. adults with high blood pressure: 0.4
- Sample size: 37 adults

**Calculator Used:**
For calculations, a TI-84 Plus Calculator may be used. Results are rounded to four decimal places.

### Part 1 of 6
**Normal Approximation for Probability:**
- **Appropriate Use:** 
  - Calculations suggest that it's appropriate to use the normal curve because \( np = 14.8 \) and \( n(1-p) = 22.2 \), both are greater than or equal to 10.

**Progress:** 0 out of 6 parts completed.

---

### Part 2 of 6
**Probability Calculation:**
- **Objective:** Find the probability that more than 45% of the sample has high blood pressure.
- **Result:** The probability is \( 0.2674 \).

**Progress:** 1 out of 6 parts completed.

### Part 3 of 6
**Updated Sample Analysis:**
- **New Sample Size:** 83 adults
- **Objective:** Find the probability that more than 41% have high blood pressure.
- **Result:** [Blank for student input]

**Progress:** 2 out of 6 parts completed.

### Part 4 of 6
**Probability of Specific Proportion:**
- **Objective:** Determine the probability that the proportion of those with high blood pressure is between 0.26 and 0.32 in a sample of 83.
- **Result:** [Blank for student input]

**Progress:** 3 out of 6 parts completed.

---

### Part 5 of 6
**Probability of Lower Proportion:**
- **Objective:** Calculate the probability that less than 27% in the sample of 83 have high blood pressure.
- **Result:** [Blank for student input]

**Progress:** 4 out of 6 parts completed.
