6. The incomes in a large population of college teachers have an extremely right-skewed distribution with mean $55,000 and standard deviation $5,000. A random sample of 50 teachers will be selected from this population to serve on a salary review committee. Can we validly use the standard Normal table to calculate the probability that their mean income will be greater than $60,000? No, because the population standard deviation is not known. O No, because the Central Limit Theorem does not apply. Yes, because the sampling distribution of x will be approximately normal. Yes, because using the standard Normal table is always appropriate
