A poll of 1081 Americans showed that 46.8% of the respondents prefer to watch the news rather than read or listen to it. Use those results with a 0.05 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.
Which of the following statements is correct? The p-value measures the probability of obtaining a test statistic as great as or greater than the value of the observed test statistic. The p-value measures the probability that the hypothesis is true. The p-value measures the probability of making a Type II error. The larger the p-value, the stronger the evidence against the null hypothesis A large p-value indicates that the data is consistent with the alternative hypothesis.
