Concept explainers
To Explain: that whether the state for performing inference about the regression model are met or not.
Answer to Problem 6E
Conditions have been met.
Explanation of Solution
Given:
There are conditions for the regression inferences are normal, equal standard deviation, random, independent and linear.
Normal: satisfied, the reason is that the samples of 16 young perches were less than 10 percent of all the young perches.
Equal standard deviation: satisfied, the reason is that the vertical spread of points in the residual figure is approximately the same everywhere.
Random: satisfied, the reason is that the subject were arbitrary assigned to a pen.
Independent: satisfied, because the sample of sixteen young perches is less than 10 percent of all the young perches.
Linear: satisfied, because of there is no enough strong curvature percent is the residual figure.
Therefore all states or conditions have been satisfied.

- please solve this problem step by step and make it quick pleasearrow_forwardWHAT IS THE CORRECT ANSWER AND WHY?arrow_forwardA common way for two people to settle a frivolous dispute is to play a game of rock-paper-scissors. In this game, each person simultaneously displays a hand signal to indicate a rock, a piece of paper, or a pair of scissors. Rock beats scissors, scissors beats paper, and paper beats rock. If both players select the same hand signal, the game results in a tie. Two roommates, roommate A and roommate B, are expecting company and are arguing over who should have to wash the dishes before the company arrives. Roommate A suggests a game of rock-paper-scissors to settle the dispute. Consider the game of rock-paper-scissors to be an experiment. In the long run, roommate A chooses rock 21% of the time, and roommate B chooses rock 61% of the time; roommate A selects paper 39% of the time, and roommate B selects paper 21% of the time; roommate A chooses scissors 40% of the time, and roommate B chooses scissors 18% of the time.

- A qualifying exam for a graduate school program has a math section and a verbal section. Students receive a score of 1, 2, or 3 on each section. Define X as a student’s score on the math section and Y as a student’s score on the verbal section. Test scores vary according to the following bivariate probability distribution. y 1 2 3 1 0.22 0.33 0.05 x 2 0.00 0.08 0.20 3 0.07 0.05 0.00 μXX = , and μYY = σXX = , and σYY = The covariance of X and Y is . The coefficient of correlation is . The variables X and Y independent. The expected value of X + Y is , and the variance of X + Y is . To be accepted to a particular graduate school program, a student must have a combined score of 4 on the qualifying exam.
