A phone company has a decision to make.  A supplier of cameras has come forward and offered lower prices than the company’s current vendor.  Before deciding whether or not to switch, the company measures a sample of cameras from the new supplier and their current supplier.  Then, they conduct a hypothesis test to see if there is a statistically significant difference in quality between suppliers.  If the results include a p-value of 0.704, should we assume that the quality is the same or different?

A safety analyst wants to compare how experienced and inexperienced drivers respond to various road conditions.  To measure driving performance, the analyst records the time in seconds that each driver uses to make steering corrections.  He questions whether or not there is a statistically significant difference in variation of “correction time” between driver types.  Based on the following plot, which was generated during a hypothesis test, what can be assumed?  

Distinguish between the two types of statistics that we discussed.

Watch the following video and, in the space below, provide the ideal number of tickets (in this example) that is likely to yield the highest revenue.  (It’s a pretty neat example of the power of probability!)    

You work in commercial real estate, and your supervisor tells you that the probability of closing an important deal is 1.15.  This would be a valid probability.

A concert promoter is planning for an upcoming event, which will take place outdoors.  He is worried that there might be rain or a nearby traffic accident, which could cause problems.  If the likelihood of rain is 15% and an accident is 18%, what is the probability that one OR the other event will occur on the day of the concert?  Your answer should be a decimal rather than a percentage.  Also, as a note, both events could occur at the same time, and to determine the likelihood of that happening, you can multiple the individual probabilities together.

A beef distributor uses the following chart to examine the percentage of fat in their beef.  The chart can be used to examine both the central tendency and variation in their data.
