a) Ozone (O3) is a major component of air pollution in many cities. Atmospheric ozone levels are influenced by many factors, including weather. In one study, the percent relative humidity and ozone levels (in ppb) were measured for a number days in a particular city. A scatterplot (with line of best fit) is provided, as is output from a regression analysis carried out on these data.

Step 1
The output from the regression analysis should provide us with the slope (m) and the y-intercept (b) of the line. The equation of the line of best fit will be in the form: $$ y = mx + b $$ where y represents the ozone levels (in ppb) and x represents the percent Show more…

An environmental agency is examining the relationship between the ozone level (in parts per million) and the population (in millions) of a number of cities. Part of the regression analysis is shown to the right. Complete parts a and b. Dependent variable is: Ozone R squared = 76.7% s = 1.700 with 16 - 2 = 14 df Variable Coefficient SE(Coeff) Intercept 19.539 1.805 Pop 6.956 1.024 a) Give a 90% confidence interval for the approximate increase in ozone level associated with each additional million city inhabitants. Each additional million residents corresponds to an increase in average ozone level of between and ppm, with 90% confidence. (Round to two decimal places as needed. Use ascending order.)

Ozone occurs at all levels of the earth's atmosphere. The density of ozone varies both seasonally and latitudinally. At Edmonton, Canada, the density $D(h)$ of ozone $\left(\text { in } 10^{-3} \mathrm{cm} / \mathrm{km}\right)$ for altitudes $h$ between $20 \mathrm{kllo}$ meters and 35 kilometers was determined experimentally. For each $D(h)$ and season, approximate the altitude at which the density of ozone is greatest. $$D(h)=-0.058 h^{2}+2.867 h-24.239 \text { (autumn) }$$
