(Round your answer to two decimal places.)Long-distance runners have contended that moderate exposure to ozone increases lungcapacity. To investigate this possibility, a researcher exposed 12 rats to ozone at the rateof 2 parts per million for a period of 30 days. The lung capacity of rats was determined atthe beginning of the study and again after the 30 days of ozone exposure. The lungcapacities (in mL) are given here:(a) If we can assume normality, is there sufficient evidence to support the conjecture thatozone exposure increases lung capacity? Use α = 0.01? b) Estimate the size of the increase in lung capacity after exposure to ozone. Use a 99%confidence interval.
