Only one fifth of one percent of circuit breakers are flawed, but if a flawed circuit breaker is used in a power plant, there is a 90% chance of an explosion. If a non-flawed circuit breaker is used, the probability of an explosion is only 5%. a. If we select a circuit breaker at random and use it in the power plant, what is the probability of an explosion

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95
