Fоr the dаtаset belоw, perfоrm these four tаsks: Create at least one sketch of the quantitative variable that can be used to check for normality. Enter the quantitative variable into your TI-84 and find the sample mean and the sample standard deviation. Report the sample mean, sample standard deviation, and the sample size all with the correct notation. Use the sample data of the quantitative variable to estimate the population mean. Compute the 95% confidence interval, "by hand", showing all calculations. Write a conclusion that interprets the confidence interval. In other words, write a sentence, in the context of your problem, that explains the meaning of the confidence interval.
