If a random sample of n = 50 is drawn from a population that is not normally distributed, then the sampling distribution of the sample mean: A.
will not be normal

B.
will follow the F-distribution

C.
is approximately normal because of Central Limit Theorem results

D.
follows the t-distribution

C

Step-by-step explanation:

because you can add and then you can change the sign or you can do the subtraction if u what to no the answer so all you need to do is to add or you can change the sign to subtraction or you can do it the hard way by multiply and then you can divide.

The End

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
