The Congressional Budget Office reports that 36% of federal civilian employees have a bachelor's degree or higher (The Wall Street Journal). A random sample of 119 employees in the private sector showed that 32 have a bachelor's degree or higher. Does this indicate that the percentage of employees holding bachelor's degrees or higher in the private sector is less than in the federal civilian sector? Use ? = 0.05.
1) State the null and alternate hypotheses.
H0: p = 0.36; H1: p ≠ 0.36
H0: ? ≤ 0.36; H1: ? > 0.36
H0: ? ≥ 0.36; H1: ? < 0.36
H0: p ≥ 0.36; H1: p < 0.36
H0: ? = 0.36; H1: ? ≠ 0.36
H0: p ≤ 0.36; H1: p > 0.36
2) What sampling distribution will you use?
3) What is the value of the sample test statistic? (Round your answer to two decimal places.)
4)Will you reject or fail to reject the null hypothesis? Are the data statistically significant at level ??
5)Interpret your conclusion in the context of the application.
