1. Consolidated Power, a large electric power utility, has built a modern nuclear power plant. They also got a new cooling system to cool the wastewater. If the mean temperature is 60 F or cooler, it means the cooling system works properly. Otherwise, they need to shut down the cooling system, and appropriate actions must be taken to correct the problem. Suppose that Consolidated Power decided to use a level of signicance of 0.05 and suppose a random sample of 100 temperature readings is obtained. The mean temperature of the sample temperature is 60.482. Assume the population standard deviation equals 2. Could you perform hypothesis testing to determine whether the cooling system should be shut down? 2. Consolidated Power, a large electric power utility, has built a modern nuclear power plant.

Otherwise, they need to shut down the cooling system, and appropriate actions must be taken to correct the problem. Suppose that Consolidated Power decided to use a level of significance of 0.05 and suppose a random sample of 25 temperature readings is obtained. The mean temperature and standard deviation of the sample temperature are 60.482 and 1.8. Could you perform hypothesis testing to determine whether the cooling system should be shut down? 3. The National Safety Council reported that 52% of American turnpike drivers are men. A sample of 300 cars traveling southbound on the New Jersey Turnpike yesterday revealed that 170 were driven by men. At 0.01 signicance level, can we conclude that more than 52% of the turnpike drivers are men
