Diano4ka-milaya [45]

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
