Q1.

Which forecasting method is better to forecast for period 7 based on Mean absolute error? Naive or exponential smoothing?

Group of answer choices

A. Exponential Smoothing

B. Naive

Q2.

Use simple linear regression analysis to find the parameters for the line that minimizes MSE for this time series.
If required, round your answers to two decimal places. Use a minus sign for negative numbers, if any.

y-intercept, b₀ =

Q3.

Use simple linear regression analysis to find the parameters for the line that minimizes MSE for this time series.
If required, round your answers to two decimal places. Use a minus sign for negative numbers, if any.

Slope, b₁ =

Q4.

Use simple linear regression analysis to find the parameters for the line that minimizes MSE for this time series.

If required, round your answers to two decimal places. Use a minus sign for negative numbers, if any.
