What effect does the circled point have on the standard deviation of the residuals?
A guidance counselor wants to determine if there is a
relationship between a student's number of absences,
x, and their grade point average (GPA), y. The data
that were collected are displayed in the scatterplot
and the least-squares regression line was calculated
One student with 2 absences has a GPA of 1.8. This
point is circled on the graph.
GPA and Absences
O This point will increase the value of the standard
deviation of the residuals because it has a large
positive residual.
O This point will increase the value of the standard
deviation of the residuals because it has a large
negative residual.
O This point will not affect the value of the standard
deviation of the residuals because it has a large
positive residual
O This point will decrease the value of the standard
deviation of the residuals because it has a large
negative residual

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
