Typical Problem and Solution

Employers may ask job applicants to take an IQ test if the test has been shown to predict performance on the job. Score on one test for the 20 to 34 age group are approximately Normally distributed with mean of 110 and standard deviation of 25. Use the Empirical Rule to answer the following questions: a) About what percent of the people in this age group have score above 110? Since 110 is the mean, and the mean is equal to the median for a normal distribution, 50% of the people in this group will have scores above the mean. b) About what percent have scores above 160? 160 is 2 standard deviations from the mean. That means that there are 2.5% (5%/2) of the scores above the mean.

To Stream or Not To Stream

Streaming server allows play of the video while it is still downloading For on-campus connections, a regular server is probably fine Over a modem at a student’s home, the videos would take all day to download.

Typical Problem & Solution

Cause of death is an important issue for life insurance companies; especially identifying the most likely causes of deaths for various demographic subgroups of the population.

16 Solution

Solution

Make a bar chart to display these data. Your chart should look something like this one, although the order of the bars is not important. It should be labeled correctly and clearly. What additional information do you need to make a pie chart? We need to know the total number of deaths in this age group in 1997. We need that information to convert the numbers into percentages to be graphed into the pie chart.
