A study was conducted of college students that stated the true average number of units that a college student enrolls in each semester is 12.7 with a true standard deviation of 6.8. Suppose you randomly sampled 40 college students and recorded the number of units that each of them were enrolled in. Use this information to answer the following question.    What is the probability that the average number of units those students from your sample were enrolled in was more than 12.9? Make sure to round your answer to 2 decimal places. For example, if your answer was 0.654321 then you would type 0.65

According to the Bureau of Labor Statistics, in 2019 U.S. households spent an average of $386.92 per month on food. Assume this data is normally distributed with a standard deviation of $112. Use this information to answer the following question.    What Z-score would correspond to a household that spent an average of $320 on food per month in 2019?  Make sure to round your answer to 2 decimal places. For example, if your answer was 87.654321 then you would type in 87.65. 

A study was conducted on the fuel economy of vehicles in the U.S. The study found that cars that ran on gasoline averaged 24.2 MPG.

Use this information to answer the following question.    What MPG would correspond to the 90th percentile of all cars in the US that run on gasoline?  Make sure to round your answer to 2 decimal places. For example, if your answer was 87.654321 then you would type in 87.65.
