All Rights Reserved. Terms of UseW VThe university data center has two main computers: computer 1 and computer 2. A new routine has recently been written for computer 1 to handle its tasks,while computer 2 is still using the preexisting routine. The center wants to determine if the processing time for computer 1's tasks is now less than that ofcomputer 2. A random sample of 11 processing times from computer 1 showed a mean of 39 seconds with a standard deviation of 19 seconds, while a randomsample of 10 processing times from computer 2 (chosen independently of those for computer 1) showed a mean of 57 seconds with a standard deviation of 20seconds.Assume that the populations of processing times are normally distributed for each of the two computers, and that the variances are equal.Can we conclude, at the 0.05 level of significance, that μ₁, the mean processing time of computer 1, is less than μ₂, the mean processing time of computer 2?Perform a one-tailed test.

At a magic shop, the salesperson shows you a coin that he says will land on heads more than 70% of the times it is flipped. In an attempt to convince you he's correct, the salesperson asks you to try the coin yourself. You flip the coin 65 times. (Consider this a random sample of coin flips.) The coin lands on heads 49 of those times. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to support the salesperson's claim that the proportion, p, of all times the coin lands on heads is more than 70%. (a) State the null hypothesis H, and the alternative hypothesis H, that you would use for the test. Ho H: 0 D=D (b) For your hypothesis test, you will use a Z-test. Find the values of np andn (1-p) to confirm that a Z-test can be used. (One standard is that np 2 10 and n(1-p) > 10 under the assumption that the null hypothesis is true.) Here n is the sample size and p is the population proportion you are testing.

Thanks to an initiative to recruit top students, an administrator at a college claims that this year's entering dlass must have a greater mean IQ score than that of entering classes from previous years. The administrator tests a random sample of 10 of this year's entering students and finds that their mean IQ score is 117, with a standard deviation of 12. The college records indicate that the mean IQ score for entering students from previous years is 113. Is there enough evidence to conclude, at the 0.10 level of significance, that the population mean IQ score, p, of this year's class is greater than that of previous years? To answer, assume that the IQ scores of this year's entering class are approximately normally distributed. Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis H, and the alternative hypothesis H,. H, :0 H, :0 (b)…
Completely abstract example: If the p-value is 0.0062 what is the conclusion (use a = 0.05)? Because the p-value is above the alpha level, we fail to reject the null hypothesis. Because the p-value is above the alpha level, we reject the null hypothesis. Because the p-value is below the alpha level, we fail to reject the null hypothesis. Because the p-value is below the alpha level, we reject the null hypothesis.
One of the advantages of understanding statistics is that you can apply the concepts to yourself. This is even easier to do during our present time because of the widespread use of wearables. Wearables are accessory devices or clothing with embedded technology that are worn by a person and used to provide feedback to the person wearing them. Examples include the Fitbit, which is worn on the wrist and gathers data such as number of steps walked, heart rate, sleeping time. Another example is Ambiotex's smart shirt which is designed for athletes and has sensors in the shirt to measure heart rate, anaerobic threshold, fitness and stress levels. There are other companies making similar products. Suppose that you are interested in the amount of sleep you get a night. Sleep is very important and there is evidence that many Americans do not get enough sleep. You hypothesize you get 6 hours of sleep a night. Using a wearable, you track your amount of sleep on 16 random nights. Test the…
