Is it safe to assume that n. 10. Round your answer to one decimal place. np(1 - P) = Test the claim: a. The null and alternative hypotheses are O Ho: p 2 0.7 O Ho: / = 0.7 Ha:p 0.7 Ha: 0.7 Ha:p # 0.7 b. The test is Select an answer V C.

Round your answer to four decimal places. e. Make a decision. O Reject the null hypothesis. O Do not reject the null hypothesis. f. Make a conclusion. O There is sufficient evidence that the proportion of people who workers indicate that they are satisfied with their job is significantly different than 70% at the o -- 0105 significance level.
