Answer:
Statement 1 => the value of x = 80, where there is a 95% confidence interval for the mean max leg press.
Statement 2 => a 95% prediction for max leg press.
Statement 3 => that the slope has 95% confidence interval
Step-by-step explanation:
So for the first statement, that is " I am 95% sure the average max leg press for girls who can bench press 80 pounds is between 337.65 and 364.84 pounds" MEANS that with the value of x = 80, where there is a 95% confidence interval for the mean max leg press.
For the second statement, that is " With 95% confidence, this model predicts that for a randomly chosen girl who can bench press 80 pounds have a max leg press between 247.70 and 454.80 pounds" MEANS a 95% prediction for max leg press.
The third statement, " I am 95% sure when a girl bench presses one more pound, her max leg press increases by between 1.15 and 3.28 pounds, on average" MEANS that that the slope has 95% confidence interval
