Chapter 8: Q.20 (page 478)

In complete sentences, give an interpretation of what the interval in Exercise 8.18 means.

Short Answer

Expert verified

We estimate with 95% confidence that the true population for the population mean weight of the heads of lettuce is between 2.112 and 2.288.

Step by step solution

01

Given Information

An interpretation of what the interval in Exercise 8.18 means.

02

Explanation

The confidence interval denotes the range of possibilities for the population parameter.

"We are 95 percent convinced that the population parameter is between X and X," is the accurate reading of a 95 percent confidence interval.

For example, we would expect these confidence intervals to encompass the genuine population mean if they were calculated.
