The problem below looks at forecasting methodologies to determine which forecasting model results in the most accurate forecasts. Accuracy is determined by the lowest mean absolute deviation. Emergency calls to the 911 system of York County for the past 24 weeks are shown below. Accurate forecasts are needed to determine the number of operators needed to staff the station. Week # of Calls 1 50 2 35 3 25 4 40 5 45 6 35 7 20 8 30 9 35 10 20 11 15 12 40 13 55 14 35 15 25 16 55 17 55 18 40 19 35 20 60 21 75 22 50 23 40 24 65 SIMPLE LINEAR REGRESSION Use all of the data, weeks 1 - 24, to calculate the regression equation for this data. Use the weeks (1-24) as the independent variable (x) and number of calls as the dependent variable (y). Once you have the equation, forecast weeks 4 through 24 (enter 4, 5, 6, etc. as the x…

Instructions An engineer responsible for a manufacturing process recorded the following data in inches about a process she is responsible for managing. 18.22 16.55 19.48 15.70 19.36 17.83 15.94 13.25 15.83 16.12 19.70 18.13 15.76 14.02 17.00 14.04 13.96 16.20 She is interested in seeing if the mean is different from the known mean of 15 inches. If she took this data randomly from 18 samples, at a significance level of 1% or 0.01, is there evidence to indicate that the mean from the sample is different from the known mean value of 15 inches? Use the attached template to provide your results which includes the following sections. 1. State the Null and Alternative Hypothesis 2. State your assumptions and how you know they are reasonable. 3. Perform the hypothesis test or indicate why a hypothesis test could not be reasonably performed. 4. Describe your results and conclusions in narrative format If it is assumed the population standard deviation is known and is equal to 1.8 1. Using your…
Detecting gypsy moths The gypsy moth is a serious threat to oak and aspen trees. A state agriculture department places traps throughout the state to detect the moths. Each month, an SRS of 50 traps is inspected, the number of moths in each trap is recorded, and the mean number of moths is calculated. Based on years of data, the distribution of moth counts is discrete and strongly skewed with a mean of 0.5 and a standard deviation of 0.7. a. Explain why it is reasonable to use a Normal distribution to approximate the sampling distribution of for SRSS of size 50. b. Estimate the probability that the mean number of moths in a sample of size 50 is greater than or equal to 0.6. c. In a recent month, the mean number of moths in an SRS of size 50 was = 0.6. Based on this result, is there convincing evidence that the moth population is getting larger in this state? Explain your reasoning.
