a research study was conducted and found that the average number of times students in the class ate fast food per week was 4.0. The 95% confidence interval was (3.5, 4.5). Interpret these findings and explain what they mean.

Solution

based on the data we are 95% confident that the number of students who ate fast food per week lie in the range of 3.5-4.5.

Another way of interpreting is that if we take 100 students in the class 95 of the students who ate fast food per week fall between 3.5 -4.5
