The school principal wants to test if it is true what teachers say - that high school juniors use the computer an average 3.2 hours a day. What are our null and alternative hypotheses? If the difference between the hypothesized population mean and the mean of the sample is large, we _ the null hypothesis. If the difference between the hypothesized population mean and the mean of the sample is small, we _ the null hypothesis. At the Chrysler manufacturing plant, there is a part that is supposed to weigh precisely 19 pounds. The engineers take a sample of parts and want to know if they meet the weight specifications. What are our null and alternative hypotheses? In a hypothesis test, if difference between the sample mean and the hypothesized mean divided by the standard error falls in the middle of the distribution and in between the critical values, we _ the null hypothesis. If this number falls in the critical regions and beyond the critical values, we _ the null hypothesis. Sacramento County high school seniors have an average SAT score of 1,020. From a random sample of 144 Sacramento High School students we find the average SAT score to be 1,100 with a standard deviation of 144.
