QUESTION 4 The following table shows the weights and prices of some whole rotisserie chickens at Price Mart. Make a scatterplot with weight on the x-axis and cost on the y-axis. Include the regression line on your scatter Find the numerical value for the correlation between weight and Explain what the sign of the correlation What is the equation of the best-fit straight line, using weight as the predictor (x) and cost as the response (y). What does the slope of the regression line tell us? Find and interpret the coefficient of determination using the original Weight (lb.)

She collected the data in the graph above from records on horses she had worked with in the past (shown by the blue dots) and fit a linear regression equation (shown by the red line). According the regression equation, as the age of the horse increases in days. the wither height in cm Select an answer v The age of the horse in days and the wither height in cm are Select an answer The slope of the regression equation is approximately 0.044. interpret the slope by completing the sentence below. As the Select an answer v increases by 1, the Select an answer V increases by The regression equation approximates the wither height by the following formula. Let d = age in days Let W = wither height in cm W = 0.044 -d +…
q1(a)Imagine that you need to introduce a new gadget such as the Apple Watch. Determine which forecasting method is appropriate for projecting the future demand of such this gadget. b)ARIMA is mostly used to forecast future values using historical time series data, as we all know. Its primary use is in short-term forecasting with at least 38-40 historical data points and a small number of outliers. If we don't have at least 38 data points, we should consider using another strategy.
Q1) Forecasting is both art and science. Describe the situations where we use Qualitative forecasting techniques and quantitative forecasting techniques

QUESTION 4 Suppose the following are the seasonal indices for the first three quarters of the year for a quarterly series: Quarter Seasonal Index Q1 72.4 Q2 85.3 Q3 109.6 Remember that the seasonal indices should average 100 so you should be able to infer the seasonal index for Q4. Furthermore, suppose that the estimated coeffcients from a regression of the deseasonalized series on Time are given below: Coefficients Intercept 2,506 Time 71.3 If the original value of the series in a Q1 was 2,040, then what is the seasonally adjusted value?
