1/20 Peints) DETAILS BBBASICSTATSACC 9.3.005 MIS A random sample of 50 binomial trials resulted in 20 successes. Test the daim that the population proportion of successes does not equal 0.50. Use a level of significance of 0.05. (a) Can a normal distribution be used for the à distribution? Explain. O Ne, ne is greater than 5, but me is less than 5 O Yes, me and mq are both greater than 5. Yes, ap and ng are both less than 5. O No, ma is greater than 5, but np is less than 5. O No, np and aq are both less than 5. (b) state the hypotheses. ONI0.51 N₁1P=0.5 ON P=0.51 M₁1P=0.5 ON P=0.51 H₁1P=0.5 ONP-0.51 N₁: p=0.5 (e) Compute. (Enter a number.) Compute the corresponding standardized sample test statistic. (Enter a number. Round your answer to two decimal places.) (d) Find the P-value of the test statistic. (Enter a number. Round your answer to four decimal places.) (e) Do you reject or fail to reject Ho? Explain. At the a At the a O At the a At the a 0.05 level, we reject the null hypothesis and conclude the data are statistically significant. 0.05 level, we reject the null hypothesis and conclude the data are not statistically significant. 0.05 level, we fail to reject the null hypothesis and conclude the data are statistically significant. 0.05 level, we fail to reject the null hypothesis and conclude the data are not statistically significant. (f) What do the results tell you? O The sample O The sample The sample O The sample Need Help? Read B value based on 50 trials is not sufficiently different from 0.50 to justify rejecting Ho for -0.05. value based on 50 trials is not sufficiently different from 0.250 to not reject H, for -0.05. value based on 50 trials is sufficiently different from 10.50 to justify rejecting for a-0.05. value based on 50 trials is sufficiently different from 0.50 to not reject H, for a 0.05. 5. 1-/20 Points) DETAILS Woh Ht BBBASICSTATBACC 9.3.015.5.
