The ages of the 175 players in a youth hockey league have the following distribution: *A distribution curve of age in years. The curve is left-skewed with a median between 12 and 13.*

Suppose that we were to take random samples of 10 players from this population and calculate the sample mean age of the players in each sample.

What will be the shape of the sampling distribution of the sample mean?

Skewed to Left

Step-by-step explanation:

The shape of the sampling distribution of the sample mean will match the shape of the parent population since the sample size is small (n=10<30), although it will be closer to normal than the parent population is.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
