Using data from a former class, give a 95% confidence interval for the difference of the population means for the amount of sleep of male and female college students. Check your conditions and include boxplots. Include the sample statistics(sample sizes, means, standard deviations), degrees of freedom, Ta/2 ,SE(standard error), E(Margin of Error) and summary sentence. Conditions Sample statistics SE E df CI Ta/2 Sentence 2. Do a hypothesis test and test the claim that there is a significant difference between the amounts of sleep between male and female college students. State the hypotheses, compute the test statistics, standardize, make a sketch, compute the p-value, state your conclusions followed by a summary statement.
