A research team wants to quantify the true relationship between an apartment's distance to campus and the cost of rent. They select a random sample of apartment complexes and measure their distance from campus in miles and their rent price in dollars per semester. A confidence interval for which of the following would be most appropriate? One mean (sigma known) One mean (sigma unknown) Mean of the differences (paired samples) Difference of two means (independent samples) One proportion. Difference of two proportions Slope of the regression line D Question 16 1 pts A high school math teacher wants to know how long a particular homework assignment takes her students. She asks 50 randomly selected students in her current semester how long it took to complete the assignment. She finds that the sample data is right skewed. Are the requirements for using a confidence interval of one mean met? No, the distribution of sample means is not normal because the data is skewed right Yes, her sample size is large enough No, her confidence level is not high enough Maybe, it will depend on what the Q-Q plot looks like
