1. Brian is a 60% free throw shooter. His parents pay for a personal coach in the hopes of improving his shooting percentage. Following the lessons from the personal coach, they watch some of Brian's practices and games and record that he makes 85 out of 130 free throws. Is this enough evidence that Brian's free throw shooting percentage following the lessons is significantly higher than it was prior to the lessons? Is this a one-tailed or two-tailed test?

A. One- tailed

B. Two-tailed

5. Brian is a 60% free throw shooter. His parents pay for a personal coach in the hopes of improving his shooting percentage. Following the lessons from the personal coach, they watch some of Brian's practices and games and record that he makes 85 out of 130 free throws. Is this enough evidence that Brian's free throw shooting percentage following the lessons is significantly higher than it was prior to the lessons?

6. Brian is a 60% free throw shooter. His parents pay for a personal coach in the hopes of improving his shooting percentage. Following the lessons from the personal coach, they watch some of Brian's practices and games and record that he makes 85 out of 130 free throws. Is this enough evidence that Brian's free throw shooting percentage following the lessons is significantly higher than it was prior to the lessons? After proceeding through the full hypothesis test, what is the final conclusion?

A. I am 95% confident that the true proportion of all free throws Brian makes following the lessons from the personal coach is significantly higher than the percentage of 60% that he made prior to the lessons.

B. With 95% confidence, I do not have enough evidence to conclude that the true proportion of all free throws Brian makes following the lessons from the personal coach is significantly higher than the percentage of 60% that he made prior to the lessons.

7. Brian is a 60% free throw shooter. His parents pay for a personal coach in the hopes of improving his shooting percentage. Following the lessons from the personal coach, they watch some of Brian's practices and games and record that he makes 85 out of 130 free throws. If a confidence interval was constructed for this data following the lessons from the personal coach, what would be true?

A. The value of 60% would fall within the interval.

B. The value of 60% would fall outside the interval.
