3. You would like to determine if there is a statistical relationship between the amount of caffein in a cup of coffee and their sales at their coffee franchises. The data is included in the set "Coffee by the Cup". Here is information about the variables. Variable Caffeine Cups Sold Measurement Amount of caffeine in one cup Number of cups of the coffee Units Milligrams Cups sold sold at all of the franchises a. Which variable is the explanatory variable and which variable is the response variable? b. Construct a scatterplot of the data. Based upon the scatterplot is there a linear relationship between the amount of caffeine in one cup of the coffee and the number of cups of coffee sold? Justify your reasoning using the scatterplot. c. Run a t-test for correlation using technology. Make sure you include the p-value and the printout. According to the t-test, is there a statistical relationship between the amount of caffeine in a cup of coffee and the number of cups sold? Justify your…

1) The question screenshot attached down below answer all and just need final answer
The problem below asks you to compare 4 different 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 Greenville 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 1. EXPONENTIAL SMOOTHING Compute the forecasts using α = .2. Calculate the MAD for weeks 4 through 24 only. Compute the forecasts using α = .6. Calculate the MAD for weeks 4 through 24 only. 2.

14. The range is defined as the: a. variability of the data with reference to extreme scores. b. the variability of the data with reference to the mean. c. variability of the data in terms of how many subjects achieved each value of the variable. d. SS/n
Lecture(10.8): The Peabody Picture Vocabulary Test has a standard score mean of 100 and a standard deviation of 15. You tested a class of grade 2 students wonderinf if these scores would be different from the population. After testing this hypotheses you decided to continue looking at this data to determine if there are any group differences based on birth order. You group the children the on whether they are the oldest chlid, middle child, or the youngest child. Here is the data based on grouped information. Oldest child: 87 84 98 104 106 91 96 92 Middle child: 65 74 62 60 73 64 71 78 Youngest child: 115 84 85 83 95 94 108 102 89 Test the hypotheses at (alpha=0.05) level of signifance using the 5 step procedure.Make sure to clearly state the null and alternative hypotheses.Round your answer to 2 decimal. You are encouraged to use the following table to help you…
