Travel Brochure Suppose you had a travel company that could take people back in time. Your time machine can take tourists back millions‚ and even billions of years. You will be developing a travel brochure to entice vacationers to come to your geologic time period or Era‚ and “enjoy” what the earth of that time has to offer. Things to keep in mind when working on this project: 1. Your travel brochure will need to include written descriptions as well as illustrations of the period/era.

Tsunamis (Japanese for “Harbor Wave”) are series of waves that are characterized by their massive wavelengths‚ often about 120 miles long‚ whereas a normal wave has one of about 333 feet‚ and destruction that they bring when they hit land. They are often called tidal waves‚ but incorrectly so. They have virtually nothing to do with the tides. Tsunamis can range from a few feet in height to over a hundred feet

Chapter 10 31. A new weight-watching company‚ Weight Reducers International‚ advertises that those who join will lose‚ on the average‚ 10 pounds the first two weeks with a standard deviation of 2.8 pounds. A random sample of 50 people who joined the new weight reduction program revealed the mean loss to be 9 pounds. At the .05 level of significance‚ can we conclude that those joining Weight Reducers on average will lose less than 10 pounds? Determine the p-value. Answer: H0: = 10 pounds
