The AMS technical services department has embarked on a quality improvement effort. Its firstroject relates to maintaining the target upload speed for its Internet service subscribers. Datacollected over the past year indicate that the upload speed is approximately normally distributedwith a standard deviation of 0.10.The technical operations department wants to ensure that the mean target upload speed for allinternet service subscribers is 0.97. Each day, upload speed was measured 50 times, with thefollowing results:0.8541.0231.0051.031.219 0.977| 1.044 0.778 1.122 1.1140.931 0.723 0.9341.012 0.695 0.869 0.734 1.131 0.993 | 0.762 0.814 1.108 0.8051.0911.086 1.1411.061.0470.80.8891.2231.0240.884 0.7990.870.898 | 0.6210.8181.113 1.2861.052 0.6781.162 0.808 1.012 0.859 0.951 1.112 1.003 0.972a.

Suppose that the quarterly sales levels among health care information systems companies are approximately normally distributed with a mean of 9 million dollars and a standard deviation of 1.4 million dollars. One health care information systems company considers a quarter a "failure" if its sales level that quarter is in the bottom 10% of all quarterly sales levels.

A new phone system was installed last year to help reduce the expense of personal calls that were being made by employees. Before the new system was installed, the amount being spent on personal calls follows a normal distribution with an average of $400 per month and a standard deviation of $50 per month. Refer to such expenses as PCEʹs (personal call expenses). Find the point in the distribution below which 2.5% of the PCEʹs fell.
The combined SAT scores for the students at a local high school are normally distributed with a mean of 1469 and a standard deviation of 296. The local college includes a minimum score of 1824 in its admission requirements. What percentage of students from this school earn scores that satisfy the admission requirement?
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%).
