Question
The image contains instructions for constructing a 95% confidence interval estimate of the mean pulse rates for adult females and males, with a table of pulse rate data on the right.

**Instructions:**

1. **Constructing Confidence Intervals:**
   - For adult females: Calculate the 95% confidence interval of the mean pulse rate and fill in the blank with the lower and upper bounds, rounding to one decimal place.
   - For adult males: Similarly, calculate the 95% confidence interval and enter the results.

2. **Comparison:**
   - Based on the calculated confidence intervals, select the correct interpretation from the following options:
     - A. Confidence intervals overlap; adult males have a significantly higher mean pulse rate.
     - B. Confidence intervals do not overlap; no significant difference.
     - C. Confidence intervals do not overlap; adult females have a significantly higher mean pulse rate.
     - D. Confidence intervals overlap; no significant difference in mean pulse rates.

**Pulse Rates Data Table:**

- **Males' Pulse Rates (beats per minute):** 
  81, 74, 48, 59, 53, 63, 53, 78, 52, 60, 73, 60, 63, 77, 80, 69, 68, 98, 45, 83

- **Females' Pulse Rates (beats per minute):**
  71, 64, 72, 71, 57, 67, 56, 78, 69, 64, 64, 97, 66, 58, 65, 56, 70, 72, 83, 59

Use these data points to calculate and interpret the confidence intervals for pulse rates of male and female adults.
