Question
Minutes per Day Spent Practicing Free Throws and Percentage of Success for Five Basketball StudentsPlayer Minutes Practicing Free Throws Percentage of SuccessAdam 15 56%Jordan 30 74%Emma 45 78%Josie 60 62%A science class at a local high school conducted an experiment with their basketball team trying to determine a correlation between time spent practicing free throws and the percentage of free throws that went through the basket successfully.

At the end of the week, each player took 50 free throws and the science class recorded the percentage of success.

Solution
The choice that best describes data from the table that supports the science class' claim is "Emma and Jordan's success rates were roughly the same." This is because despite Emma practicing 15 minutes more than Jordan each day, their success rates were very similar (78% for Emma and 74% for Jordan). This suggests that the additional practice time did not significantly improve Emma's success rate, supporting the class' claim that increasing practice time doesn't necessarily improve the rate of success when it comes to free throws.

When shooting two free throws, the chance that a basketball player makes her first free throw is 70%. If she makes her first free throw, her confidence goes up and there is a 75% chance that she will make her second free throw. But, if she misses her first free throw, her confidence goes down and there is only a 50% chance that she will make her second free throw. Find the probability of each event below. Round each probability to four decimal places. You may find it useful to sketch yourself a tree diagram. (a) she makes both free throws? (b) she misses both free throws? (c) she makes exactly one of the two free throws? (d) she makes at least one of the free throws?
Samantha makes 65% of all free throws she attempts. What is the probability she will miss her next shot?
