A box of mass m = 0.50 kg vibrates back and forth on a spring which obeys Hooke’s Law. The box sits on a frictionless horizontal surface and moves with simple harmonic motion. The position of the box is given by the equation x = A cos(120 t), where A = 0.015 meters, and t is measured in seconds. What is the total mechanical energy of the box+spring system?

For each of the scenarios below, pick the simulation method (random permutation or bootstrapping) that would be appropriate to build the sampling distribution needed for the given research question. A corporation receives progress reports from employees across ten different franchise locations within a particular geographical area. Does average employee performance differ across those ten locations? A random sample of adults is given a battery of tests designed to measure their working memory capacity. What can we say about the average working memory capacity in the adult population at large? Across a random sample of single-family US households, is there a relationship between family size (number of children and adults living in the same house) and household income? Patients with PTSD are randomly assigned to either a group therapy or individual therapy. Does the proportion of patients who complete therapy differ between group-based and individual therapy?

Use the following scenario to answers Questions 23 - 25: Suppose we would like to determine if the average amount spent per customer for dinner at a new restaurant in town is more than $20.00. A sample of 49 customers over the week was randomly selected and the average amount spent was $20.60. Assume that the population standard deviation is known to be $2.50. Question 23 Set up the null and alternative hypotheses. $H_0: \mu = 20.60$ $H_A: \mu > 20.60$ $H_0: \mu > 20$ $H_A: \mu = 20$ $H_0: \mu > 20$ $H_A: \mu < 20$ $H_0: \mu = 20$ $H_A: \mu > 20$ 2 pts
