A local restaurant was trying to figure out the best way to advertise to attract new customers from this town. The owner had a set amount of money to spend on advertising and they were trying to figure out if it was better to invest in advertisements on social media or television commercials. They conducted a survey of 500 local residents to gauge if they spent more time on social media or watching television. Out of the 500 residents who were surveyed, 222 of them stated that they spent more time on social media than watching television.    Use this information to carry out the appropriate hypothesis test at the

Eliza had a long commute to work each day and she was always worried about running late. When it came to distance, both drives were the same number of miles from her home, but one of them had a few more stoplights on her way. She wanted to find the most consistent route so she could know exactly how long it would take her to go to work each day. She decided to travel each route 28 times and recorded how long it took each time to make an informed decision. On her 28 trips using route A, she took an average of 40 minutes with a standard deviation of 5.4 minutes. On her 28 trips using route B, she took an average of 40 minutes with a standard deviation of 5.9 minutes. Assume the commute times using both routes are normally distributed.    Use this information to carry out the appropriate hypothesis test at the

The average height for an NCAA Division 1 men’s basketball player is 77 inches. Assume this data is normally distributed with a standard deviation of 8 inches. Use this information to answer the following question.    What is the probability that a randomly selected NCAA D1 men’s basketball player is at least 78.5 inches tall?  Make sure to round your answer to 2 decimal places (For example, if your answer was 0.654321 then you would type 0.65)

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. Assume this data is normally distributed with a standard deviation of 3.7 MPG. Use this information to answer the following question.    What MPG would correspond to the 33rd 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. 

Consider a town where the average age of all individuals is 35.6 years old with a standard deviation of 13.7 years. Suppose you were to randomly select 50 individuals from this town as part of a study.    What is the probability that the average age of the 50 individuals in your study would be less than 40 years old or greater than 30 years old? Make sure to round your answer to 2 decimal places. For example, if your answer was 0.654321 then you would type 0.65

The average height for an NCAA Division 1 men’s basketball player is 77 inches. Assume this data is normally distributed with a standard deviation of 8 inches. Use this information to answer the following question.    What is the probability that a randomly selected NCAA D1 men’s basketball player is shorter than 71.5 inches tall?  Make sure to round your answer to 2 decimal places (For example, if your answer was 0.654321 then you would type 0.65)

A local community college was interested in gauging how interested their students were in building a parking garage on campus. However, they knew that a large number of their students primarily took online courses, so they wanted to ensure that they compared the responses between students taking in-person classes and online classes. They decided to randomly survey 180 students taking in-person classes and 220 students taking online classes. They asked them whether or not they were interested in a parking garage being built on campus. Out of 180 students taking in-person classes, 108 of them stated they were interested. Out of the 220 students taking online classes, 117 mentioned they were interested.    Use this information to carry out the appropriate hypothesis test at the

A study was conducted that found 83% of all teenagers in the US own at least one video game console. Suppose you were to randomly sample 30 US teenagers.   What is the probability that exactly 25 of them would own at least one video game console? Use a binomial distribution to answer this question. Make sure to round your answer to 2 decimal places (For example, if your answer was 0.654321 then you would type 0.65)

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 less than 13.4?  Make sure to round your answer to 2 decimal places. For example, if your answer was 0.654321 then you would type 0.65
