Problem 1 Given: Ho: The proportion of employees in a shoe factory who smoke cigarette is 30%. (Ho: p= .30) Ha: The proportion of employees in a shoe factory who smoke cigarette has increased to 30%. (H.: p > .30) a = 0.01 Computed z-statistic: Zcom = 2.56 and Critical z- value: z tab = 1.282 DECISION: Since the computed test statistic Zoom= 2.56 in the rejection region, the null hypothesis (Ho). CONCLUSION: Therefore, we conclude that at 0.01 level of significance, evidence to conclude that
