Which one of the following statements about confidence intervals is false? Given the same sample of data, a 99% confidence interval will be wider than a 95% confidence interval. The size of the population affects the width of a confidence interval. The sample statistic determines the center of the confidence interval. The value of z* affects the width of a confidence interval. The general format of a confidence interval is “sample statistic ± margin of error.”
You are interested in finding a 99% confidence interval for the average commute that non-residential students have to their college. The data below show the number of commute miles for 12 randomly selected non-residential college students. Round answers to 3 decimal places where possible. 18 20 20 24 5 28 10 13 5 24 11 11 b. With 99% confidence the population mean commute for non-residential college students is between ? and ? miles. c. If many groups of 12 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group. About ? percent of these confidence intervals will contain the true population mean number of commute miles and about ? percent will not contain the true population mean number of commute miles.

A box model is used to calculate a confidence interval in the following scenario: Statistics club at TYHS wants to know the average time students in TYHS spent on preparing for their standardized exams. They sampled 100 students from TYHS. They want to construct a confidence interval for the average time that students in TYHS spent on preparing for their standardized exams. For each of the following quantities in the box model, select the answer if the quantity is random, not fixed. Leave the quantities that are fixed unselected. Group of answer choices. You can select more than one answer the proportion of 0's in the box model the EV and SE of the sample average the average time of every student in TYHS spent on preparing for their standardized exams the sample average of students spent on preparing for their standardized exams
