**Confidence Intervals: Understanding and Calculation**---**Instructions:**1. For each problem below, decide whether it describes a confidence interval for a proportion or a confidence interval for a mean.2. Apply the correct formula to calculate the confidence interval in the format of an estimate ± margin of error.---**Example Problem:**During the 2016 season, Mark Williams played in 18 golf matches and used his driver club 126 times, hitting his drives an average of 278 yards per drive, with a standard deviation of 15 yards per drive. Calculate a 95% confidence interval for the distance he was able to hit his driver club in that season.---**Explanation:**In the problem provided, we need to determine and calculate the confidence interval for the mean distance Mark Williams hit his driver club, using the given data. 1. **Identify the type of confidence interval:** This is a confidence interval for a mean because we are looking to estimate the average distance (a continuous variable) with a given standard deviation.2. **Formulate the confidence interval:** The confidence interval for the mean is usually calculated using the formula: \[ \text{Confidence Interval} = \bar{x} \pm Z \left(\frac{\sigma}{\sqrt{n}}\right) \] Where: - $\bar{x}$ is the sample mean. - $Z$ is the Z-score corresponding to the desired confidence level. - $\sigma$ is the standard deviation. - $n$ is the sample size.3. **Plug in the values:** \[ \bar{x} = 278 \text{ yards per drive} \] \[ \sigma = 15 \text{ yards} \] \[ n = 126 \text{ drives} \] For a 95% confidence level, the Z-score ($Z$) is approximately 1.96.4. **Calculate the margin of error:** \[ \text{Margin of Error} = 1.96 \left(\frac{15}{\sqrt{126}}\right) \] \[ \text{Margin of Error} \approx 1.96 \left(\frac{15}{11.225}\right) \] \[ \text{Margin of Error} \approx
