A health spa has advertised a weight reducing program and has claimed that the average participant in the program loses at least 20 pounds. A somewhat overweight executive is interested in the program but is skeptical about the claims and asks for some hard evidence. The spa allows him to select randomly the records of ten participants and record their weights before and after the program.

Test whether the average weight loss is at least 20 pounds.

Participant Before After

Ross Erickson 189 170

Josh Way 202 179

Laura Ewok 220 203

Luke Haas 207 192

Brandon Bott 194 172

etc. etc. etc.

State H0 and H1. You MUST show the five-step process for determining H0 and H1. (1 pt.) Be very careful how you handle the 20 pound difference! The variable with the larger numbers MUST be on the left.
