A biologist believes the number of pups per wolf dens in southwestern United States is now less than 6 (in the past the average number of pups per wolf den has been 6). A study is conducted and the number of pups in wolf dens in the southwestern United States is recorded below for 16 wolf dens. 5 85 8. 6. 7 93 4 3 4 6 Note: Ex=90 and Ex = 554 Can you conclude the biologist is correct? Assume the distribution follows a bell-shaped curve. Test at a = 0.05.

Because the total population in 2050 is much larger than the Comparison of Population in the United States in 1950 and 2050 (in millions of persons) 1950 population, comparing percentages in each age group is clearer than comparing counts. Make a table of the Age Group 1950 2050 percentage of the total population in each age group for both Under 10 years | 29.3 | 56.2 1950 and 2050. 10 to 19 years 21.8 || 56.7 Only one age group in 1950 represents a larger percentage of the population than it does in 2050. For that age group, 20 to 29 years | 24.0 | 56.2 30 to 39 years | 22.8 | 55.9 determine the difference of the percentages between 1950 and 2050.

Suppose a researcher collects data on the air pollution levels, measured in milligrams per cubic meter, for both urban and rural areas in 35 states. The data is plotted with urban air pollution levels on the horizontal axis and rural air pollution levels on the vertical axis. Nevada is an outlier in the ?x‑direction. What must be true about this state? The urban air pollution levels for this state are much higher or lower than the rest of the states in the data set. The rural air pollution levels for this state are much higher or much lower than the rest of the states in the data set. This state is an influential observation. The rural air pollution levels for this state are much higher or lower than other states in the data set that have similar urban air pollution levels. The absolute value of the residual of this state is large.

A study found that among the 2300 college students who drank energy drinks daily 850 of them binge drank alcohol on a monthly basis. In contrast, 240 of the 1387 students who do not drink energy drinks daily binge drank alcohol monthly. Fill in the contingency table and determine the percentage of college students who drink energy drinks daily among those who DO NOT binge on alcohol. Binge Drink Alcohol Don't Binge Drink Alcohol Total Drinks Energy Drink 850 1450 2300 Does not Drink Energy Drink 240 1147 1387 Total 1090 2597 3687
