Math Problem Statement
The probability of a high school basketball team winning any game is 58%. This team is in a six-game tournament, and the games are played independently of one another. Let X represent the number of games the team might win in this tournament. What are the mean and standard deviation of X?
Mu Subscript x Baseline = 2.52, Sigma Subscript x Baseline = 2.15 Mu Subscript x Baseline = 3.48, Sigma Subscript x Baseline = 1.21 Mu Subscript x Baseline = 3.48, Sigma Subscript x Baseline = 1.46 Mu Subscript x Baseline = 5, Sigma Subscript x Baseline = 1.46
Solution
To solve this problem, we need to calculate the mean () and standard deviation () for a binomial distribution.
Binomial Distribution Parameters
- Number of trials (): 6 (6 games in the tournament)
- Probability of success (): 0.58 (58% chance of winning each game)
The formulas for the mean and standard deviation of a binomial distribution are:
Step 1: Calculate the Mean ()
Step 2: Calculate the Standard Deviation ()
Final Answer
The correct option is: Mu Subscript x Baseline = 3.48, Sigma Subscript x Baseline = 1.21
