I want to estimate the population mean number of times that adults eat breakfast in a week. I spoke with 12 coworkers, and the numbers were 7, 5, 5, 7, 2, 3, 7, 5, 1, 0, 7, 6. Calculate a 95% confidence interval for the population mean (round 3 decimal places).
The proportion of students who pass a placement exam at a college has been 0.64. With hopes toincrease that proportion the college hired a company to provide a brief refresher class before the test is given.A sample of 250 students got selected for the study and 168 of these students passed the exam. At the 5%significance level do the data provide enough evidence to claim the population proportion of students passingthe test will be higher with the company’s refresher class? what is the hypthesis and test stastic?
Researchers are studying whether the proportion of homeschooled children in district 1 (considered 1) is less than the proportion of homeschooled children in neighboring district 2 (considered as 2). To test the theory info was gathered: district 1 had 600 students of which 90 were homeschooled. District 2 had 550 students of which 99 were homeschooled. What is the 95% confidence interval for the difference proportion between district 1 and 2? A. (-0.086, 0.026) B. (0.143, 0.217) C. (0.113, 0.187)
