H1: =, >, <, or ≠ _________________ year (s). Since the P-value is less than or equal to, or more than or equal to the significance level, reject or do not reject the null hypothesis. There is or is not sufficient evidence to support the claim that actress are generally younger when they won the award than actors. Since the confidence interval contains only zero, positive number values, or only negative number values, reject or warrent rejection of the null hypothesis.Test the claim about the population mean, μ, at the given level of significance using the given sample statistics.

Find the sample size needed to give, with 95% confidence, a margin of error with +/- 6% when estimating a proportion. Within +/- 4%. Within +/- 1%. (Assume no prior knowledge about the population proportion p). Comment on the relationship between the sample size and the desired margin of error.
