MaRussiya [10]

Answer:

free throws = 6

2 points shots = 3

Step-by-step explanation:

To do this we will have 2 incognitas.

x = number of free throws

y = number of shots of 2 points

x(1) + y(2) = 12

he says he made twice as many free throws as 2 points

x = 2y

2y(1) + y(2) = 12

2y + 2y = 12

4y = 12

y = 12/4

y = 3

x = 2y

x = 2*3

x = 6

free throws = 6

2 points shots = 3

We always take the alternate hypothesis such that it should satisfy the given statement.

And the null hypothesis can be equal to mean or other than that is given in alternate hypothesis.

So, hypothesis :

$H_0:\mu =45\\\\H_a:\mu\geq 45$
