Wildlife conservationists are concerned that the deer population might not be constant across the national forest. the scientists found that there were 144 deer in a 16-square-mile area of the forest. in another part of the forest, conservationists counted 117 deer in a 13-square-mile area. yet a third conservationist counted 216 deer in a 24-square-mile plot of the forest. do conservationists need to be worried?
a. why does it matter if the deer population is not constant in a certain area of the national forest?
b. what is the population density of deer per square mile?
the unit rate of deer per 1 square mile is
constant of proportionality:
explain the meaning of the constant of proportionality in this problem:
c. use the unit rate of deer per square mile (or y/x) to determine how many deer there are for every 207 square miles.
d. use the unit rate to determine the number of square miles in which you would find 486 deer.

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
