For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. A random sample of 5616 physicians in Colorado showed that 3278 provided at least some charity care (i.e., treated poor people at no cost). A USE SALT (a) Let p represent the proportion of all Colorado physicians who provide some charity care. Find a point estimate for p.

For each 1000-foot increase in elevation, how many fewer frost-free days are predicted. We want to determine how many fewer frost-free days are predicted when the elevation increases by 1000 ft. Predictor Coef SE Coef T PConstant 316.27 28.31 11.24 0.002Elevation -32.660 3.511 −8.79 0.003S = 11.8603 R-Sq = 95.1% Here, ŷ is the number of frost-free days and the variable x is the elevation measured in thousands of feet. Therefore, each 1000 ft increase in elevation results in a 1 unit increase in x. fill in the blank in part a/part b. a) Recall that the slope of a least-squares line, ŷ = a + bx, indicates how much ŷ changes when x changes by 1 unit. In part (a), we determined the slope of the line is b = −32.660. This means that for each unit that x increases, the value of ŷ decreases by _______ units. b) Therefore, when the elevation increases by 1000 ft there are _______ fewer frost-free days.
