1. Kenny plays basketball and his season average for making his free throws is .8. This means he makes 80% of his free throws. Using his long term free throw success rate, answer the following questions.
MAKE SURE YOU STUDY MY NOTES AND THE SECTIONS ON BINOMIAL RANDOM VARIABLES.
If Kenny shoots 10 free throws, what is the probability he makes exactly 5?
If Kenny shoots 4 free throws, what is the probability he makes less than 3 of them?
If Kenny shoots 15 free throws, what is the probability me makes at least 10 of them?
If Kenny shoots 3 free throws, what is the probability he makes at least one of them?
If Kenny shoots 6 free throws, what is the probability he makes all 6?
If Kenny shoots 30 free throws, how many do we expect him to make?
If Kenny shoots 6 free throws, what is the probability he makes only one of them?
What is the probability Kenny will not make a free throw?
2 The heights of all American men are normally distributed with a mean of 69 inches and a standard deviation of 2.6 inches. These data are from a long term 4 year measurement study.
Population data from International Data Base, United States Census Bureau.
Answer the following about this study and the probabilities. The probabilities were calculated using the TI graphing calculator. If you use the table of standardized scores, find the value that is closest to your value. It is recommended you complete the lesson on Z scores posted in the Moodle Statistics class.
What height places an American male in the shorter 5% of all American heights?
P ( X < 70 )
What height places an American male in the top 20% of all American male heights?
The random variable, “heights of all American men” is either discrete or continuous, select from the list.
P ( X ≥ 64 )
The value “2.6 inches” is either a parameter or a statistic, select one from the list.
P ( 65 < X < 72 )
