Question

let's say that is has been established that a 95% confidence interval for the mean number of oranges eaten per week pe person is 0.8 to 2.6. True or false: this means that 95% of all people eat between 0.8 and 2.6 oranges per week

Answer 1

False

Explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

In this question:

95% confidence interval for the mean number of oranges eaten per week per person is 0.8 to 2.6.

This means that we are 95% sure that the true population means for the number of oranges eaten per week per person is 0.8 to 2.6, not that 95% of all people eat between 0.8 and 2.6 oranges per week. So the answer is False.
