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

Answer:
Z = -6.3
Step-by-step explanation:
Given that:
![\mathbf{H_o :p= 0.28}](https://tex.z-dn.net/?f=%5Cmathbf%7BH_o%20%3Ap%3D%200.28%7D)
![\mathbf{H_o :p < 0.28}](https://tex.z-dn.net/?f=%5Cmathbf%7BH_o%20%3Ap%20%3C%200.28%7D)
Since the alternative hypothesis is less than 0.28, then this is a left-tailed hypothesis.
Sample sixe n = 800
= 0.217
The standard error ![S.E(p) = \sqrt{\dfrac{p(1-p)}{n}}](https://tex.z-dn.net/?f=S.E%28p%29%20%3D%20%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D)
![S.E(p) = \sqrt{\dfrac{0.28(1-0.28)}{800}}](https://tex.z-dn.net/?f=S.E%28p%29%20%3D%20%5Csqrt%7B%5Cdfrac%7B0.28%281-0.28%29%7D%7B800%7D%7D)
![S.E(p) \simeq0.015](https://tex.z-dn.net/?f=S.E%28p%29%20%5Csimeq0.015)
Since this is a single proportional test, the test statistics can be computed as:
![Z = \dfrac{\hat p - p}{\sqrt{\dfrac{p(1-p)}{n}}}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cdfrac%7B%5Chat%20p%20-%20p%7D%7B%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D%7D)
![Z = \dfrac{0.217- 0.28}{0.01}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cdfrac%7B0.217-%200.28%7D%7B0.01%7D)
Z = -6.3
