Chapter 6: q.34 (page 357)

How well does it fit? (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.

A large auto dealership keeps track of sales made during each hour of the day. Let X= the number of cars sold during the first hour of business on a randomly selected Friday. Based on previous records, the probability distribution of Xis as follows:

The random variable Xhas mean μX=1.1and standard deviation σX=0.943.

Suppose the dealership’s manager receives a 500bonus from the company for each car sold. Let Y = the bonus received from car sales during the first hour on a randomly selected Friday. Find the mean and standard deviation of Y.

76. Rhubarb Suppose you purchase a bundle of 10bare-root rhubarb plants. The sales clerk tells you that on average you can expect 5%of the plants to die before producing any rhubarb. Assume that the bundle is a random sample of plants. Let Y= the number of plants that die before producing any rhubarb. Use the binomial probability formula to find
P(Y=1). Interpret this result in context.

Kids and toys Refer to Exercise 4. Calculate and interpret the standard deviation of the random variable X. Show your work.

19. Housing in San Jose How do rented housing units differ from units occupied by their owners? Here are the distributions of the number of rooms for owner-occupied units and renter-occupied units in San Jose,
California:

Let X = the number of rooms in a randomly selected owner-occupied unit and Y = the number of rooms in a randomly chosen renter-occupied unit.
(a) Make histograms suitable for comparing the probability distributions of X and Y. Describe any differences that you observe.
(b) Find the mean number of rooms for both types of housing unit. Explain why this difference makes sense.
(c) Find the standard deviations of both X and Y. Explain why this difference makes sense.

Explain whether the given random variable has a binomial distribution.

Lefties Exactly 10%of the students in a school are left-handed. Select students at random from the school, one at a time, until you find one who is left-handed. Let V=the number of students chosen.
