Assume the heights in a male population are normally distributed with mean 70.3 inches and standard deviation 4.1 inches. then the probability that a typical male from this population is between 5 feet 6 inches and 6 feet tall is (to the nearest three decimals) which of the following pairs of heights most closely divides the population into three equally probable groups (i. e., 1/3 below the first, 1/3 above the second, and 1/3 in between)? a. 5 feet 7.9 inches, 6 feet 1.2 inches b. 5 feet 8.5 inches, 6 feet 0.1 iches c. 5 feet 8.8 inches, 6 feet 0.7 inches d. 5 feet 7.6 inches, 5 feet 11.9 inches

In 2009, there were 1570 bears in a wildlife refuge. in 2010, the population had increased to approximately 1884 bears. if this trend continues and the bear population is increasing exponentially, how many bears will there be in 2018?

An equation in slope-intersept form the lines that passes thought (-8,1) and is perpindicular to the y=2x-17.

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
