Chapter 6: Q. 6.71 (page 269)

Obtain the z-score for which the area under the standard normal curve to its left is0.025.

Short Answer

Expert verified

The z-score under the standard normal curve with the area 0.025to its left is -1.96.

Step by step solution

01

Given information

The given area is0.025.

02

Explanation

The given area is 0.025

Begin by looking for the 0.025area in the table's body. The matching z-score for the area is -1.96. As a result, the z-score under the standard normal curve with the area0.025 to its left is -1.96, which can be rendered as

Below is a section of the standard normal table that is relevant:

Most popular questions from this chapter

We have provided a normal probability plot of data from a sample of a population. In each case, assess the normality of the variable under consideration.

Bouted Eagles. The rare booted eagle of western Europe was the focus of a study by S. Suarez et al, to identify the optimal nesting habitat for this raptor. According to their paper "Nesting Habitat Selection by Booted Eagles (Hienieefus pennatus) and Implications for Management" (Jamal of Applied Ecolesy, VoL. 37. pp, 215-223). the distances of such nests to the nearest marshland are normally distributed with a mean of 4.66km and a standard deviation of 0.75km. Let Y be the distance of a randomly selected nest to the nearest marshland.

Determine and interpret

a. P(Y>5).

b. P(3鈮�Y鈮�6).

Answer true or false to each statement. Give reasons for your answers.

a. Two variables that have the same mean and standard deviation have the same distribution.

b. Two normally distributed variables that have the same mean and standard deviation have the some distribution.

Briefly, for a normally distributed variable, how do you obtain the percentage of all possible observations that lie within a specified range?

Explain in detail what a normal probability plot is and how it is used to assess the normality of a variable.
