A group of researchers studied the effect of acid rain on wildlife and collected n = 12 samples from streams in different States. They recorded the pH (X) of the water (i.e. units above pH 7), and the BCI, a measure of biological diversity (Y). The data obtained is summarized below. DATA: Observation 1 2 3 4 5 6 7 8 9 10 11 12 pH above 7 (X) 0.65 0.50 0.93 0.86 1.02 0.94 1.16 1.24 1.30 1.45 1.85 1.89 Units of BCI (Y) 14.5 22.9 15.8 38.3 18.9 20.0 21.4 23.8 23.6 25.2 27.3 29.4 Find the correlation coefficient between pH and BCI (round to the nearest hundredth; place your answer in the box below)

The mode is the only measure of central tendency that is appropriate to utilize for a variable measured with which scale of measurement? ordinal nominal interval ratio

I need help finding the distance the stick traveled. It’s average acceleration is 1.5 mph.

Mean Temperature (°C) The following scatterplot shows the mean annual carbon dioxide (CO,) in parts per million (ppm) d) What is the meaning of the slope of this equation? measured at the top of a mountain and the mean annual air temperature over both land and sea across the globe, in degrees Celsius (C). Complete parts a through h on the right. O A. For every degree that the mean temperature increases, CO, levels increase by 0.004 ppm. 16.800 O B. For every 0.004 ppm increase in CO, levels, the mean temperature increases by 1°C. 16.725 OC. For every 1 ppm increase in CO, levels, the mean temperature increases by 0.004°C. 16.650 O D. The slope does not have a meaningful interpretation in the context of this problem. 16.575 16.500 e) What is the meaning of the y-intercept of this equation? 337.5 CO, (ppm) 350.03 325.0 362.5 A. For every 1 ppm increase in CO, levels, the mean temperature increases by 0.004°C. Click here to view the regression output. O B. When the CO, level is 0 ppm, the…
