**Explanation for Students:**
In this problem, you're asked to calculate a 95% confidence interval for the mean weight of all bags of potatoes. The weights given are from a sample of four bags, and the assumption is that the data follows a normal distribution. The task is to use these sample weights to estimate the range in which the true mean weight of the population of potato bags is likely to fall, 95% of the time. Complete the calculations by rounding your results to the nearest hundredth.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F19a66268-dac5-4e12-b8e8-fcb4c369153b%2Fcf847d0b-25ed-4d8f-9eeb-7874f0bf803f%2F00o4xi6_processed.png&w=3840&q=75)
