Question: you would like to determine if the population probability of...

Question details

You would like to determine if the population probability of success differs from 0.70. You find 62 successes in 80 binomial trials. implement the test at the 1% level of significance. (Y u may find lt useful to reference the appropriate table: z table or t table) a. Select the null and the alternative hypotheses. Hg: P s8.78; HA: P8.78 O He: p 0.78; HA: p < 8.78 b. Calculate the sample proportion. (Round your answer to 3 declmal places.) Sample proportion c. Calculate the value of test statistic. (Round Intermedlate calculatlons to at least 4 declmal places and final answer to 2 declmal places.) Test statistic d. Find the p-value. Op-value<0.01 0.01 s p-value<0.025 0.025 s p-value <o.05 0.05 s p-value 0.10 O p-value 0.10 e. At the 1% significance level, what is the conclusion? OReject He since the p-value is smaller than significance level. O Reject Hg since the p-value is greater than significance level. Do not reject Hg since the p-value is smaller than significance level. Do not reject He since the p-value is greater than significance level.
