A researcher wants to estimate the average systolic blood pressure of female college students to within 2 points with 90% confidence. To determine the sample size required, she needs to know the population standard deviation, which is 4.8. Here are the steps to calculate the sample size: 1. Determine the z-value corresponding to a 90% confidence level. For a 90% confidence interval, the z-value typically used is 1.645 (this can be found in z-tables or through statistical software). 2. Use the formula for calculating the sample size for estimating a mean with a known standard deviation: \( n = \left( \frac{z \cdot \sigma}{E} \right)^2 \) Where: - \( n \) is the sample size. - \( z \) is the z-value corresponding to the desired confidence level. - \( \sigma \) is the population standard deviation. - \( E \) is the desired margin of error. 3. Plug the values into the formula: \( n = \left( \frac{1.645 \cdot 4.8}{2} \right)^2 \) \( n = \left( \frac{7.896}{2} \right)^2 \) \( n = (3.948)^2 \) \( n \approx 15.586 \) 4. Since the sample size must be a whole number, round up to the nearest whole number to ensure the desired confidence level is maintained. Rounding up gives you: \( n = 16 \) So, the researcher should select a sample size of 16 female college students to estimate the average systolic blood pressure within 2 points with 90% confidence.
