STATISTICS AND PROBABILITY (PLEASE SHOW your COMPLETE & CLEAR solutions) RATE WILL BE GIVEN A company produces mosquito repellants that have a period of effectiveness that is approximately normally distributed with a mean of less than 300 hours and a standard deviation of 12 hours. A sample of 40 repellants was taken and the average period of effectiveness is computed as 294 hours. Is this sufficient evidence to conclude that the company's claim is true at a=0.01? Answer the following: a. State the null and alternative hypothesis (in words and in symbols) and identify the claim. b. Find the critical value/s.
