Forest Fires and Acres Burned Numbers (in thousands) of forest fires over the year and the number (in hundred thousands) of acres burned for 6 recent
years are shown. The regression line equation is y'=-18.779+0.761x. The standard error of the estimate is sest 9.55. Find the 80% interval when x=60.
Round intermediate answers to three decimal places. Round your final answers to two decimal places as needed.

- As an industrial engineer, you intend to use linear trend (or linear regression) method to solve a forecasting problem. You have decided to use the equation of y = m(x) + c to establish the relationship between the sales (y) and the related month (x). It is known that 8 consecutive months data (Jan to Aug) were used and they resulted to the following parameter values of m = 320 and c = 1017. Using the regression technique, estimate the percentage of sales improvement from December this year to June next year.arrow_forward2 balls are drawn in a succession without replacement from an urn containing 5 white balls and 6 black balls.Let b be the random variable representing the number of black balls.construct the probability distribution of the random variable B.arrow_forwardPlease make the exact scoot of this graph.
