Average

In mathematics, everyone must have heard the term average in one place or other. Almost all types of calculation require taking out an average. In everyday life, the term is used for denoting a certain amount that can be said to be a typical quantity for multiple people or objects. In other words, if a group of people possesses a certain object, then the average gives us an idea regarding the quantity of the object possessed by each person. However, this is solely based on mathematical calculation. It is important to note that most people will not strictly have the average value in a group.

Question

Wind speeds in the midwest are known to have a highly skewed right distribution
with mean u = 13.7 mph and standard deviation o = 5.8.
a) If we take a random sample of size 17 from this population distribution
for wind speeds what distribution will the data distribution follow? What
effect should we expect if we increase the sample size to 452?

wind speeds, what distribution will the sample mean X follow? If possible,
determine the value for the mean and standard deviation.
c) If we take a random sample of size 17 from the population distribution
for wind speeds, what distribution will the sample mean X follow? What
