The NCHS reported that the mean total cholesterol level was 203 for all adults in 2003. Patients (n=15) were enrolled in a 6-week study to test the efficacy of a new drug. Use the five-step hypothesis testing procedure to determine if the new drug was effective in reducing the cholesterol levels compared to the historical mean. At the end of 6 weeks: ◦n = 15 ◦X ̅ = 195.9 ◦s = 28.7

During the busy season, it is important for the shipping manager at ShipMundo to be able to estimate the time it takes the loading crew to load a truck. The shipping manager has found that she can model the load times using a normal distribution with a mean of 152 minutes and a standard deviation of 15 minutes. Use this table or the ALEKS calculator to find the percentage of load times between 116 minutes and 149 minutes according to the model. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%).
