Answer:

a) H0 : P = 0.07

Ha : P ≠ 0.07

b) p -value = 0.1770

Step-by-step explanation:

P = 7% = 0.07

x (result ) = 7 , n = 163

p = x / n = 7 / 163 = 0.043

a) Using a significance level ( ∝ ) of 0.05, estimate the appropriate hypothesis

H0 : P = 0.07

Ha : P ≠ 0.07

conduct a Z- test statistic

Z = ( p - P ) / $\sqrt{\frac{P(1-P)}{n} }$

= ( 0.043 - 0.07 ) / $\sqrt{\frac{P(1-P)}{n} }$ = - 1.35

Critical value ( Z₀.₀₂₅ ) = ± 1.96

we fail to reject H0 given that | z | < Zcritical because there is not enough evidence to conclude that proportion change

b) Determine the p-value of the test

P-value = P ( | Z | > Z )

= 2 * P ( Z < -1.35 )

= 0.1770

The p-value ( 0.1770 ) > ∝ ( 0.05 ) hence we fail to reject H0 ( i.e. the conclusion agrees with part a above )
