ONCE AGAIN I WILL GIVE BRAINLIEST (02.02 MC)

Monthly grocery cost based on the average number of shopping trips is predicted using the least-square regression line, ŷ = 275.3 + 90.7x, where ŷ represents the predicted monthly expense and x represents the average number of trips. A shopper visits the grocery store an average of 3.2 times and has a monthly cost of $520. What is the residual for the shopper?
Select one:
a. 45.54
b. 76.47
c. −45.54
d. −76.47
e. 90.7

A statistician wants to determine the relationship between typing speed, in words per minute, and the time, in minutes, it takes to type one page of a specific book. Twenty-five trials are completed and the correlation coefficient between typing speed and time is determined to be -0.622. Therefore, slower typing speed was related to greater time. How is the correlation affected if the units for time are changed from minutes to seconds?
Select one:
a. The correlation and time measurement would change proportionally to one another.
b. The correlation would stay the same because the change in units for time would have no effect on it.
c. The correlation would increase because changing the units for time would result in an increase in time values.
d. It is impossible to determine the amount of change experienced by the correlation.
e. The correlation would decrease because only the units for one of the variables changed.

The probability of tails of a weighted coin is 0.65. The number of tails is noted each of the 15 times the coin is tossed. If this procedure is repeated 100 times, what type of distribution is simulated?
Select one:
a. A sampling distribution of the sample proportion with n = 15 and p = 0.65
b. A sampling distribution of the sample proportion with n = 100 and p = 0.65
c. A binomial distribution with n = 15 and p = 0.65
d. A binomial distribution with n = 2 and p = 0.65
e. There is not enough information to determine the type of distribution.
