**Understanding Confidence Intervals: Estimating Expenditures on Birthday Gifts**A recent survey involving 23 participants sought to determine the amount of money that parents spent on their child's last birthday gift. The responses generated a roughly bell-shaped distribution, with a calculated mean expenditure of $31 and a standard deviation of $3. Utilizing this data, we aim to estimate the typical expenditure a parent might incur for a birthday gift, considering a 95% confidence level.To achieve this estimate, we need to provide answers rounded to one decimal place and include both the point estimate and the margin of error.**Task: Provide the point estimate and margin of error.**Point Estimate: [ ______ ] ± Margin of Error: [ ______ ]

From the given information we find the 95% confidence interval.

Answered: roughly bell-shaped with a mean of $31…
