A survey of 50 young professionals found that they spent an average of $21.68 when dining out, with a standard deviation of $12.11. Can you conclude statistically that the population mean is greater than $27? Use a 95% confidence interval. The 95% confidence interval is As $27 is V of the confidence interval, we V conclude that the population mean is greater than $27. (Use ascending order. Round to four decimal places as needed.)

Now change the 'Normal' choice to 'Exponential' This changes the underlying population from one that has a normal distribution to one that is very not normal. Change the sample size to 5 and run samples. a. How well do the 95% confidence intervals do at capturing the true population mean when samples sizes are small? b. Now change the sample size to 40 and run samples. Does a larger sample size mean that the intervals are more likely to capture the true population value? Why? Note THIS is an important concept and relates back to the Sampling Distribution of Sample Means and how the SDSM changes as sample size increases when the population is not normal.
