Answer:
The alternative hypothesis is 
.
The critical value is 
Step-by-step explanation:
It is claimed that proportion in favor of proportion A is greater than 60%.
This means that at the null hypothesis, we test if the proportion is of at most 60%, that is:
At the alternative hypothesis, we test if the proportion is more than 60%, that is:
What is (are) the critical value?
The critical value is the value of Z with a p-value 1 subtracted by the standard significance level of 0.05, since we are testing if the mean is more than a value, so, looking at the z-table,

Answer:
x = 47°
Step-by-step explanation:
From the picture attached,
CPD is a straight line.
Therefore, ∠CPB and ∠DPB is a linear pair of angles.
And linear pair of angles are supplementary.
By the property of linear pair of angles,
m∠CPB + m∠DPB = 180°
133 + x = 180
x = 180 - 133
x = 47°
Answer:
She made 17 three-point shots.
Step-by-step explanation:
Let t represent the number of three-point shots she made.
Since, she made a total of 87 shots (two- or three-point shots), the number of two-point shots will be 87-t.
The points from three-point shots:
→ 3t (1)
The points from two-point shots:
→ 2(87-t) (2)
Since, her total point was 191, the sum of equation 1 and equation 2 must be equal to 191.
→ 3t + 2(87-t) = 191
→ 3t + 174 - 2t = 191
→ t = 17
