Suppose the happiness of six teams has been measured on a scale that has a normally distributed population with a standard deviation of 3. Just for fun, you sample 33 six teams from this population and obtain a mean happiness of 23.95 and a standard deviation of 3.5006. Using an alpha value of α = 0.01, is this observed mean significantly different than an expected happiness of 22? (Two Tailed)

State Null and Alternate Hypotheses.
Apply test.
Write your conclusion using critical value approach and p value approach.
Construct a 95% confidence interval to estimate the population mean. Write and justify your conclusion.

You are riding on a Ferris wheel while standing on a scale. The scale normally reads 1500 lbs. (Did I mention you're a robot made of incredibly heavy metal?) While you are riding, you notice your weight on the scale changing. At the TOP of the Ferris wheel, you weigh only 1430 lbs. The Ferris wheel has a diameter of 230 m. How much time does it take the Ferris wheel to make one full turn? (Give answer in seconds).

We usually assume that your weight as measured by a scale is equal to the magnitude of the gravitational force that the earth exerts on you. Because of the rotation of the earth, however, the scale reading can actually be slightly different from your true weight. Which of the following accurately describes this effect?
