Assume that two populations are independent and normally distributed with means μ1, H2 and standard deviations 01, 02, respectively. (a) What is the point estimate of 1-2? What is the margin of error E associated with this estimate (use a = 0.05)? (b) Find 95% confidence interval for μ1 - 2. (c) Test Ho 1 μ2 = 0 vs H₁₁₂ <0 at a = 0.01.

Here is a sample of the hours of sleep of 20 random college students. A)Is there enough at the 2% level that the average hours a college student studies each week is greater than 7.5 hours? Show work. B) Hypothesis: C) Show what is given: D) List your Ho and Ha: E) Prepare and Check conditions 1-3 (show work): F) What is the critical value from the table? G) Compare you p-value to the significance level: H) Interpret and wire conclusion: I) Confidence interval conditions 1&2: J) We are __% confident the average hours a college student studies each week is between ___ to ___ hours.
Listed below are times (in minutes and seconds) that a statistics instructor recorded while riding a bicycle for five laps through each mile of a 3-mile loop. Use a 0.10 significance level to test the claim that the samples are from populations with the same median. What do the data suggest?
