A researcher reports that the average salary of assistant professors in a certain state is $42,000. A random sample of 30 assistant professors in that state has a mean salary of $43.260 and a standard deviation of $5230. Assuming that the population is normally distributed, test the claim using a = 0.05. There is enough evidence to reject the null hypothesis. The claim is true. O There is enough evidence to reject the null hypothesis. The claim is false. There is not enough evidence to reject the null hypothesis. The claim is probably true. O There is not enough evidence to reject the null hypothesis. The claim is probably false.
