Students tracked how many hours they slept a night for a month. The mean was 8.37 with a standard deviation 1.84. Assume that the distribution is normal. Find the probabilities (round to three decimal places): Probability a student gets more than 9.3 hours of sleep

Draw a boxplot from the prior question. 

Students tracked how many hours they slept a night for a month. The mean was 8.37 with a standard deviation 1.84. Assume that the distribution is normal. Find the probabilities (round to three decimal places): Probability a student gets less than 6.75 hours of sleep. 

Use the following sample data set and solve for the standard deviation (round to two decimal places): 71, 76, 78, 77, 86, 82, 88, 83, 73, 77, 80, 72, 79, 81, 89, 82
