This null hypothesis is: Select one: a. Not rejected with a signicance level of 5%. b. Rejected with a signicance level of 5%, but not with a signicance level of 1%. c. Rejected with a signicance level of 1%, but not with a signicance level of 0.1%. d. Rejected with a signicance level of 0.1% The correct answer is: Rejected with a signicance level of 0.1% Use the function "connt" in order to construct a condence interval to the slope of the regression line. The value 0: Select one: a. Belongs to the 95% condence interval. b. Does not belongs to the 95% condence interval. The correct answer is: Does not belongs to the 95% condence interval.
