Answer:
B. There is not sufficient evidence to support the claim that the proportion of male golfers is less than 0.6.
Step-by-step explanation:
The proportion of male golfers is less than 0.6.
At the null hypothesis, we test if the proportion is of at least 0.6, that is:
At the alternative hypothesis, we test if the proportion is of less than 0.6, that is:
Fail to reject the null hypothesis.
This means that there is not sufficient evidence to conclude that the proportion is less than 0.6, and thus the correct answer is given by option B.

We know that
equilibrium point is a point where demand curve and supply curve (S) intersect each other
so, D=S
so, equilibrium point is at x=40
and price at that point is p=45
we know that
revenue = price*quantity
revenue = 40*45
so, the store will make $1800 by selling ceiling fans...........Answer

A retrospective study
Step-by-step explanation:
When you’re looking back, it’s called retrospective. He’s taking his old results and using them to map his success rate with high accuracy.

Cross multiply
10 x 9 = 90
3 x k = 3k
make an equality
90 = 3k
divide both sides by 3
90/3 = k
simplify
30 = k
