7. A group of university students are interested in comparing the average age of cars owned by students and the average age of cars owned by faculty. They randomly selected 25 cars that are own by students and 20 cars that are owned by faculty. The average age and standard deviation obtained from the students' cars are 6.78 years and 5.21 years, respectively. The sample of faculty cars produced a mean and a standard deviation of 5.86 years, and 2.72....

5. We are interested in comparing the proportions of cars that have all-wheel-drive (AWD) between different sizes of cars produced in 2015. In a sample of n = 47 small cars, 9 of these cars had AWD. Also, 9 cars had AWD in a sample of n2 = 34 midsized cars. Conduct a hypothesis test to assess whether there is sufficient evidence of a difference between the proportions of small and midsized cars having AWD. Use a 2-sided alternative hypothesis...

3. A real estate company is interested in assessing the average sale price of houses in Santa Cruz. After collecting data for 600 home sales in 2015, they compute that the mean sale price was 672,492 dollars with a standard deviation of 97,200 dollars a) What is the standard deviation of the mean sale price? b) Test the hypothesis that the mean sale price is $600,000 against the alternative that it not at the 95% confidence level. c) Test the...

Suppose we are interested in analyzing how much people spend on travel during the summer. We know that on average, people spend $1005 on travel with a population standard deviation of $1740. Suppose we take a sample of 30 people and we find that the average spent from that sample is $1850. We are interested in seeing if the amount spent on travel is increasing. What is the standard error? What is the margin of error at 90% confidence? Using...

(6 points) Cars on Campus. Statistics students at a community college wonder whether the cars belonging to students are, on average, older than the cars belonging to faculty. They select a random sample of 23 cars in the student parking lot and find the average age to be 8.5 year with a standard deviation of 5.3 year. A random sample of 23 cars in the faculty parking lot have an average age of 3.4 years with a standard deviation of...

Length of Movies ~ A movie data base claims that the average length of movies is 117 minutes. A researcher collected a random sample of 160 movies released during 2010-2015. The mean length of those movies is 118.65 minutes and the standard deviation is 8.83. Note: Numbers are randomized in each instance of this question. Pay attention to the numbers in this question. The researcher wonders if the actual mean length of movies released during 2010- 2015 is more than...
