A research team has been contracted to learn some information about what type of new coaster passholders would like to see constructed at the park. Determine the type of sample used: The research team decides to use the numbers on the passholder cards and use a random number generator to determine what passholders to gather information from.

A new restaurant has just opened at the entrance to an amusement park. The owner wants to know what local residents think and what tourists going to the park think of the restaurant. 100 local residents and 100 tourists going to the park were surveyed. They were asked to rate the restaurant on a scale of 1 to 10 with 1 being “very unpleasant” and 10 being “amazing.” The sample mean rating for local residents was 6.4 with a sample standard deviation of 1.5. The sample mean rating for tourists going to the park was 7.0 with a sample standard deviation of 2.0. Suppose the owner wants to test a claim that the ratings of local residents and tourists going to the park are not the same. The numeric value of the t-statistic would be: . Remember this says numeric value and so the sign, positive or negative, does not matter. The p-value for the test would be: The calculation for the critical test statistic (t crit) at a level of significance of 0.05 for this situation would be: What action should be taken?

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?
