Answer:

Well by looking at this proportion the answer might be 1.0217

Answer:

Probability of proportion will greater than 47% = 0.6915

Step-by-step explanation:

Given data:

population proportion p = 0.46

sample proportion b \hat p = 0.47

sample size be n = 622

Probability of proportion will greater than 47%

P(\hat p > 0.47) = P[\fraca{\hat p - p}{\sqrt{p(1-p)/n}}]

= P[z > {\frac{0.47 -0.46}{\sqrt{0.46(1-0.46)/622}}]

                          = P(z >0.500)

from standard z table

= 0.6915
