I only really need help with parts D, E, F, G
please!
1) A golf pro wanted to learn the relation between the club-head
speed of a golf club (measured in miles per hour) and the distance
(in yards) that the ball will travel. He realized that there are
other variables besides club-head speed that determines the
distance a ball will travel (such as club type, ball type, golfer,
and weather conditions). To eliminate the variability due to these
variables, the pro used a single model of club and ball. One golfer
was chosen to swing the club on a clear, 70-degree day with no
wind. The pro recorded the club-head speed and measured the
distance that the ball traveled and collected the data seen
below.
Club-head speed 100 102 103 101 105 100 99 105
Distance 257 264 274 266 277 263 258 275
(a) Construct a scatter plot of the data.
(b) Compute the correlation coefficient.
(c) State the equation of the least squares line. Draw the line
on the scatter plot. State at least two ordered pairs that are on
the line.
(d) Interpret the slope and intercept of the least squares
regression line.
(e) Predict the distance a golf ball will travel when hit with a
club-head speed of 103 miles per hour. Does the least squares
regression line underestimate or overestimate this distance?
Explain your answer.
(f) Is it reasonable to use the least squares regression line to
predict the distance for a club-head speed of 80? Explain your
answer.
(g) What portion of distance is explained by the club-head
speed
