Question
Can you answer whats blank?
Transcribed Image Text:The Congressional Budget Office reports that 365% of federal civilian employees have a bachelor's degree or higher (The Wall Street Journal). A random sample of 122 employees in the private sector showed that 34 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
divilian sector? Use e- 0.05.
What are we testing in this problem?
O single proportion
O single mean
(a) What is the level of significance?
State the null and alternate hypotheses.
O H.: p - 0.36; H:p> 0.36
O H:: p - 0.36; H: p+ 0.36
O Hg: - 0.36; HM< 0.36
O Hg: - 0.36; H:M> 0.36
O Hg: H- 0.36; H: M 0.36
O Hg: P - 0.36; H:p< 0.36
(b) What sampling distribution will you use? What assumptions are you making?
O The standard normal, since np < 5 and ng < 5.
O The Student's t, since np > 5 and ng > 5.
O The standard normal, since np > 5 and ng > 5.
O The Student's t, since np <5 and ng < 5.
What is the value of the sample test statistic? (Round your answer to two decimal places.)
(c) Find for estimate) the Pvalue
O P-value > 0.250
O 0.125 < Pvalue < 0.250
O 0.050 < P-value < 0.125
O 0.025 < Pvalue < 0.050
O 0.005 < Pvalue < 0.025
O Pvalue < 0.O05
