Chapter 6: q.34 (page 357)

How well does it 铿乼? (3.2) Discuss what s, r2, and the residual plot tells you about this linear regression model.

Short Answer

Expert verified

From the provided plot, no particular pattern is being followed. Thus, it could be said that the provided model is a good fit.

Step by step solution

01

Step 1: Given Information

It is given in the question that,

The residual plot is:

02

Explanation

The value of the sin the supplied output is 12.55. The prediction error is estimated to be around 12.55.

The coefficient of determination depicts the variance in the response variable that is described by the predictor variable. The coefficient of determination is 55.8%in this case.

As a result, the least square line can explain 55.8percent of the variation in the response variable.

87. Airport security The Transportation Security Administration (TSA) is responsible for airport safety. On some flights, TSA officers randomly select
passengers for an extra security check before boarding. One such flight had 76辫补蝉蝉别苍驳别谤蝉鈥�12in first class and 64in coach class. Some passengers were surprised when none of the 10 passengers chosen for
screening were seated in first class. Can we use a binomial distribution to approximate this probability? Justify your answer.

A small ferry runs every half hour from one side of a large river to the other. The number of cars Xon a randomly chosen ferry trip has the probability distribution shown below. You can check that 渭X=3.87and 蟽X=1.29.

(a) The cost for the ferry trip is $5. Make a graph of the probability distribution for the random variable M=money collected on a randomly selected ferry trip. Describe its shape.

(b) Find and interpret 渭M.

(c) Compute and interpret 蟽M.
