Has the marrying age of a man changed over the years? The United States Bureau of the Census takes a formal
count of everyone in the U. S. every 10 years and has provided the following data that gives the median age of an
American man at the time of his first marriage.
Year 1910 1920 1930 1940 1950 1960 1970 1980 1990 2000
Median Age 25.124.6 24.3 24.3 22.8 22.8 23.2 24.7 26.126.8
What does a rate of change of zero mean in this situation?
a. The median age of a man at the time of his first marriage is, on the average, constant
b. The median age of a man at the time of his first marriage is, on the average, decreasing.
C. The median age of a man at the time of his first marriage is, on the average, increasing.
d. The rate of change cannot be zero in this situation.

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
