listed below are the numbers of forest fires (in thousands) and the acres that were burned (in hundred thousands) during a year.

x 70 65 58 48 83 65 56 42

y 28 41 22 27 53 19 30 18

find the value of the linear correlation coefficient r and use a significance level of a=0.05 to determine whether there is a significant linear correlation between the two variables.

Find the best predicted value (including units) for the number of acres burned given that there were 60 thousand fires.

The average number of acres burned by forest and range fires in a large New Mexico county is 4,300 acres per year, with a standard deviation of 750 acres. The distribution of the number of acres burned is normal. [4 decimal places] What is the probability that between 2,500 and 4,200 acres will be burned in any given year? * 2 points Your answer What is the probability that less than 4000 acres were burned? * 2 points Your answer...

The average number of acres burned by fires in New Mexico County is assumed to be normally distributed with a mean of 9000 and a standard deviation of 695 acres. You are told that the probability of the number of acres burned between 9350-R and 9350+R is .7802. Find R. (Hint: Draw a picture to see the area along with the given probability. Can Goal-Seek or trial and error help you find the value of R?) How would I solve...
