Expert Solution

Null hypothesis H0: Proportion of employees rate the management as participatory is 0.5. That is p = 0.5

Alternative hypothesis H1: Proportion of employees rate the management as participatory is greater than 0.5. That is p > 0.5

Sample proportion, = 80 / 200 = 0.4

Standard error of proportion, SE = = 0.0354

Test statistic, z = ( - p) / SE = (0.4 - 0.5) / 0.0354 = -2.82

P-value = P(z > -2.82) = 0.9976

Since, p-value is greater than 0.05 significance level, we fail to reject null hypothesis H0 and conclude that there is no strong evidence that Proportion of employees rate the management as participatory is greater than 0.5 or majority of employees rate the management as participatory.
