Question

For all problems provide the following and show work:

Null hypothesis; Alternative hypothesis; appropriate variables such as variance, sample mean etc; a sketch of the normal distribution curve with the appropriate critical value(s), critical (reject) area(s), and test value shown; a written statement on whether the null hypothesis is to be reject based on the provided evidence. Please ask for clarification on these directions if needed.

2) A random sample of the number of games played by individual NBA scoring leaders is shown. Is there sufficient evidence to conclude that the variance in games played differs from 35? Use = 0.05. Assume the variable is normally distributed.

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.
