-50 + 18

First, simplify -50 + 18 (a calculator would be best for this problem). / Your problem should look like: -32

Answer: -32 (B)

B. is the correct answer. - 32 is correct because when you are adding a positive and a negative always remember same signs add and keep different signs subtract.

Answer:

2.60

Step-by-step explanation:

Given that:

n = 1600

$\hat p = 0.34$

$P_o = 0.31$

The test statistics can be computed as:

$Z = \dfrac{\hat p - P_o}{\sqrt{ \dfrac{P_o\times (1-P_o) } {n} }}$

$Z = \dfrac{0.34-0.31}{\sqrt{ \dfrac{0.31 \times (1-0.31) } {1600} }}$

$Z = \dfrac{0.03}{\sqrt{ \dfrac{0.31 \times (0.69) } {1600} }}$

$Z = \dfrac{0.03}{\sqrt{ \dfrac{0.2139} {1600} }}$

$Z = 2.60$
