A starting player for a major college basketball team made only 5% of her free throws last season. During the off season she worked on developing a softer shot in the hope of improving her free throw accuracy. In the first eight games this season she made 22 out of the 42 free throws she attempted. Did she improve her accuracy?
Homework Answers
Ans:
H0:p=0.5
Ha:p>0.5
Sample proportion=22/42=0.5238
Test statistic:
z=(0.5238-0.5)/sqrt(0.5*(1-0.5)/42)
z=0.31
p-value=P(z>0.31)=0.378
Fail to reject the null hypothesis.
There is not sufficient evidence to conclude that she improve the accuracy.

Leroy, a starting player for a major college basketball team, made only 27.5% of his free throws last season. During the summer he worked on developing a softer shot in the hope of improving his free-throw accuracy. In the first eight games of this season, Leroy made 29 free throws in 40 attempts. Let p be his probability of making each free throw that he shoots this season. (a) State the null hypothesis H. that Leroy's free-throw probability has remained...

A college basketball player makes 80% of his free throws. At the end of a game, his team is losing by two points. He is fouled attempting a 3-point shot and is awarded three free throws. Assuming each free throw is independent, what is the probability that he makes at least one of the free throws?

Sandy Carlson, who plays for her college basketball team, had an 80% free throw percentage in the previous fall semester. On average, Sandy made 8 out of every 10 free throws. If we are to randomly select 80 free throws she has made throughout the season and then record the number of successes in these 80 free throws, then the standard deviation of the sample proportion is: A) 0.001 B) 0.80. C) 0.04. D) 0.94. E) 0.06.

12. (10 points) A college basketball player makes 90% of his free throws. Assuming free-throw attempts are independent. Over the course of the season, he will attempt 100 free throws. a) Use binomial distribution to find the exact probability that the number of free throws he makes is between 85 and 95, inclusive b) Check the conditions for using the normal appreciation to the binomial distribution. c) Use normal approximation to estimate the probability that the number of free throws...

Suppose a basketball player makes 80% of her free throws. Let X be the number of free throws that she makes in the next n = 10 attempts. Note that X has a binomial distribution with n = 10 and p = 0.8. Find the probability that she makes 6 of her 10 attempts, denoted by P(X = 6).

Suppose you have a friend on the school basketball team but, unfortunately, he is not a good free throw shooter. Over the course of his career, he has only made 40% of his shots. Otherwise, he is a good player and gets fouled a lot so he shoots 10 free throws a game, on average. In the biggest game of the season, he does very well and makes 6 out of 10 free throw attempts. ?
