A coaster enthusiast group decided to have an outing at the local amusement park.  Some members of the group want to test a claim that a proportion less than 0.10 are over the age of 70.  A random sample of 100 members was taken and it was found that 6 of the 100 were over the age of 70.  Take alpha to be 0.05. The z-statistic would be:  The p-value would be: The critical z-statistic (z crit) would be:  What action should be taken?

The train ride is always a favorite at the amusement park.  A sample of 100 trips taken by the train around the park found that sample mean number of persons riding the train was 107 with a sample standard deviation of 45.    Suppose some researchers want to test a claim that the mean number of persons riding was not 120.  What would the hypotheses be? 

The height at which a hot air balloon company flies its balloons is normally distributed with a mean of 1000 feet and a standard deviation of 50 feet. What percent of the hot air balloon flights will fly higher than 1125 feet?  What percent of the hot air balloon flights will fly lower than 900 feet?    A balloon flying at 1075 feet would have a z-score of?
