1. A Texas House representative proposed placing solar panels on all public schools to increase green energy and reduce energy costs for districts. Suppose a manufacturer’s panels will be purchased only if real world results of the proposed panels have an average efficiency rating greater than 18%. A random selection of 32 panels results in a mean efficiency rating of 0.182 with a standard deviation of 0.006. Is there sufficient evidence at the 5% significance level to purchase the proposed panels?
