In a simple linear regression study between two variables x ( the independent variable) and y (the dependent variable), a random large sample is collected and the coefficient of correlation r = −.98 is calculated. A)Which of the following conclusion may be made? Group of answer choices x and y are almost perfectly correlated, and y increases as x is increased. x and y are almost perfectly correlated, and y decreases as x is increased. x and y are moderately...
17) The following linear trend expression was estimated using a time series with 17 time periods (that is, the values of tare 1, 2, V,= 129.23.8t Calculate a 95% prediction interval for the value of Y at time period t 18 (i.e, h 1 period ahead). Use the fact that the average of the time values is 9, the standard deviation of the time values is s 5.05, and the regression standard error se 0.841. Take all calculations and the...
For a simple linear regression model, significance of regression is: Group of answer choices the variability of the observed Y-values from the predicted values. a hypothesis test of whether the regression coefficient ß1 is zero. a measure of how well the regression line fits the data. a measure that determines if the linearity assumption is satisfied
