Mark the following statement True or False. If you believe that the statement is false, briefly explain why you think it is false. To guarantee a margin of error of 0.034 for the population proportion p, a survey needs to have at least 1,050 respondents (assuming that the results are presented with 95% confidence).

Mark the statement below as True or False. If you believe that it is false, briefly say why you think it is false. Larger surveys convey a more accurate impression of the population than smaller surveys. Choose the correct answer below. A. The statement is false. Smaller surveys convey a more accurate impression of the population than larger surveys. B. The statement is false. Sample size does not change the impression of the population given by a survey. C. The...

Determine whether the following statements are true or false. If the statement is false, then explain why the statement is false or rewrite the statement so that it is true. A Type I error in a hypothesis test occurs when we fail to reject the null hypothesis when the null hypothesis is actually false. A Type II error occurs when we reject the null hypothesis when the null hypothesis is actually true.
