A family of statisticians is trying to decide if they can afford for their child to play youth baseball. The cost of joining a team is normally distributed with a mean of $750 and a standard deviation of $185. If a sample of 40 teams is selected at random from the population, select the expected mean and standard deviation of the sampling distribution below.oz= $185 oz= $29.25 oz = $4.63 nu2 = $118,59 0 nu2 = $18.75 nu2= $750

Sagot :

If a sample of 40 teams is selected at random from the population, the expected mean is $750 and the standard deviation is $29.25

The mean of the cost of joining a team = $750

Standard deviation = $185

A sample of 40 teams is selected at random from the population

The expected standard deviation = [tex]\sqrt{\frac{185^2}{40} }[/tex]

= $29.25

Here the cost of joining a team is normally distributed with a mean of $750

Here the distribution of the cost of joining is normal the mean of the sample distribution, so it will be equal to the mean of the population

The mean = $750

Therefore, the standard deviation is $29.25 and the mean is $750
