A random sample of 50 binomial trials resulted in 20 successes. Test the claim that the population proportion of successes does not equal 0.50. Use a level of significance of 0.05.MY NOTESPRA USE SALT(a) Can a normal distribution be used for the p distribution?

(Round your answer to two decimal places.)(d) Find the P-value of the test statistic. (Round your answer to four decimal places.)(e) Do you reject or fail to reject Ho? Explain.At the a 0.05 level, we reject the null hypothesis and conclude the data are statistically significant.At the a- 0.05 level, we reject the null hypothesis and conclude the data are not statistically significant.At the a 0.05 level, we fail to reject the null hypothesis and conclude the data are statistically significant.At the a 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?The sample p value based on 50 trials is sufficiently different from 0.50 to not reject Ho for a- 0.05.The sample p value based on 50 trials is not sufficiently different from 0.50 to not reject Ho for a- 0.05.The sample p value based on 50 trials is sufficiently different from 0.50 to justify rejecting Ho for a = 0.05.The sample p value based on 50 trials is not sufficiently different from 0.50 to justify rejecting Ho for a- 0.05.

A poll of 1086 Americans showed that 47.1% of the respondents prefer to watch the news rather than read or listen to it. Use those results with a 0.01 significance level to test the claim that fewer than half of Americans prefer to watch the news rather than read or listen to it. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution.
