Statistical Concepts: Data Simulation Confidence Intervals Normal Probabilities Short Answer Writing Assignment All answers should be complete sentences. We need to find the confidence interval for the SLEEP variable. To do this, we need to find the mean and then find the maximum error. Then we can use a calculator to find the interval, (x – E, x + E)…….. Give and interpret the 95% confidence interval for the hours of sleep a student gets. (5 points) Give and interpret the 99% confidence i...

Statistical Concepts: Probability Binomial Probability Distribution Calculating Binomial Probabilities Plotting the Binomial Probabilities Create plots for the three binomial distributions above. You can create the scatter plots in Excel by selecting the data you want plotted, clicking on INSERT, CHARTS, SCATTER, then selecting the first chart shown which is dots with no connecting lines. Do this two more times and for graph 2 set Y equal to ‘one half’ and X to ‘success’, and...
