Question

Assume that the shortest 25% of the basketball players in this club have to attend for a compulsory training session.

What is the probability that out of 40 selected basketball players in the club, 5 or fewer of them attend the compulsory training session?

What assumption would you need to check? Please choose from below

- The boxplots indicate that the samples are fairly symmetric and the spreads are similar, so we can assume both sets of data come from normal distributions with the same spread

- Since nπnπ and n(1−π)n(1−π) are both ≥5, the Central Limit Theorem applies and we can assume that p arises from a normal distribution

- The points are randomly scattered around a straight line, so the assumptions of linearity and constant spread are satisfied. The shape of the histogram indicates that the residuals come from a normal distribution

- None of these

-The shape of the histogram indicates that the scores may be from a normal distribution and/or the sample size is reasonably large so the sample mean will be from a normal population

What is the value of the test statistic? (2 dp)

What is the probability out of 40 selected basketball players in the club, 5 or fewer of them attend the compulsory training session? (provide your answers between a value 0 to 1 and for 4 decimal places)

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
