In a survey, 18 people were asked how much they spent on their most recent child's birthday. The results were roughly bell-shaped with a mean of $35 and a standard deviation of $5. Use the Theory-based inference applet to find the 98% confidence interval to estimate the value of the population parameter and answer the questions below. We are 98% confident that the average (mean) amount that all people spent on their most recent child's birthday is between_____ dollars and _____ Give your answers rounded to one decimal place. (b) The value of the sample statistic is (c) The margin of error is (d) The confidence interval can be written
