A large national bank charges local companies for using theirservices. A bank official reported the results of a regressionanalysis designed to predict the bank's charges(Y)—measured in dollars per month—for servicesrendered to local companies. One independent variable used topredict the service charge to a company is the company's salesrevenue (X)—measured in millions of dollars. Datafor 21 companies who use the bank's services were used to fit themodel:
E(Y) = β0 +β1X
The results of the simple linear regression are provided below.
= -2,700 + 20X, SYX = 65, two-tailed p value = 0.034(for testing β1)
Interpret the estimate of σ, thestandard deviation of the random error term (standard error of theestimate) in the model.
A)About 95% of the observed service charges equal their correspondingpredicted values.
B)About 95% of the observed service charges fall within $65 of theleast squares line.
C)For every $1 million increase in sales revenue, we expect a servicecharge to increase $65.
D)About 95% of the observed service charges fall within $130 of theleast squares line.

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
