Referring to the Table above, the Holt-Winters method for forecasting with smoothing constant of 0.2 for both level and trend will be used to smooth the wine sales. The smoothed values of the level and trend for 1993 are _________ and ________, respectively.
a. 356 and 86
b. 406.8 and 57.84
c. 398 and 61.25

A case-control study is performed to study the relationship between esophageal cancer and an exposure (exposure A).
Use simple exponential smoothing with α = 0.33 to forecast battery sales for February through May. Assume that the forecast for January was for 22 set of tires.
This linear regression model was fitted to a sample of size 50 to produce the following regression equation: yhat = 145 + 1.2x1 + 300x2.
One should never use a regression line to predict the dependent response variable when the independent value is outside of the data range of the original data set that was used to fit the line.
The new independent variable improves the predictive power of the regression model.
What is the null hypothesis? Use a = 0.05 .
Create a histogram showing the distribution of symptom scores in this sample. Is this a skewed distribution? If so, is it skewed to the left or to the right?
