A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 100 students and observed that they had a mean of 102 hours. Assume the variance is known to be 16. A level of significance of 0.05 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic.
- Need help calculating the margin of error for the question below. I show n=100, sigma = 1, and 95% prob equls a z score of 1.96 for z_alpha/2. Just having issues calcuating the Margin of Error value. The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took these 100 customers to check out was 3 minutes. It is known that the standard deviation of the population of checkout times is 1 minute. With a 0.95 probability, the sample mean will provide a margin of error of 0.196. If we wanted to cut this margin of error in half, how many customers would we need to include in our sample?Hydronos is a Greek manufacturer of yogurts that have gained popularity in the United States, so it has recently built a U.S. production plant and distribution center. To ensure that it complies with U.S. environmental standards, Hydronos is planning to implement efforts to reduce emissions and other industrial waste at its manufacturing plants using a program called Green-100. Green-100 covers all company procedures, from reducing manufacturing emissions, to how the lights are controlled in the plant, to how the truck drivers complete their routes. For example, under the new Green-100 guidelines, Hydronos has measured the amount of fuel drivers need to complete their routes for traveling at moderate speeds. If drivers choose to drive at higher speeds, they will need to pay for any extra fuel they use. Hydronos also has plans to install speed governors in its fleet of trucks to ensure that the drivers do not exceed speeds of 80 miles per hour. Mangements' claim that the new technology…Hydronos is a Greek manufacturer of yogurts that have gained popularity in the United States, so it has recently built a U.S. production plant and distribution center.

- Mr. Ferdinand is a well-known entrepreneur who sells fresh organic beef to persons in the localcommunity. Customers love the quality of meet that Mr. Ferdinand sells so they tend torecommend his product to other people. Recently, Mr. Ferdinand has been running out of beefto sell to his customers. One customer suggests to him that he must use past sales records toforecast demand for his beef so that he can meet his customers' demand.I. Using a numerical example, demonstrate to Mr. Ferdinand how he can use a three-week and a four-week weighted moving average to forecast demand for his beef.II. Show how Mr. Ferdinand can test the accuracy of his forecast. III. Explain to Mr. Ferdinand two ways in which he can benefit from doing a forecast for his beef.(c) Based on what we know about Observation B, if the cutoff value is lowered to 0.2, what happens to the values of sensitivity and specificity? Explain. Use the ROC curve to estimate the values of sensitivity and specificity for a cutoff value of 0.2. If required, round your answers to three decimal places. Do not round intermediate calculations. Answer Part C, there are no other parts here. I have the sensitivity already and is equal to 1. What is the specificity??If you are not 100% sure you are right, do not attempt this is frustrating. The cutoff value has changed from 0.5 to 0.2. The sensitivity is 1 which is correct. I need help with the specificity. Sensitivity does not equal 1/14 and specificity does not equal 1/31 so don't answer that and do not answer any other parts just answer part C.The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.05 level that the drug stays in the system for more than 399 minutes. For a sample of 81 patients, the mean time the drug stayed in the system was 401 minutes. Assume the standard deviation is known to be 21. Step 1 of 5: Enter the hypotheses: Step 2 of 5: Enter the value of the z test statistic. Round your answer to two decimal places. Step 3 of 5: Specify if the test is one-tailed or two-tailed. Step 4 of 5: Enter the decision rule. Step 5 of 5: Enter the conclusion.
