In an experiment to determine the effect of ambient temperature on the emissions of oxides of nitrogen(NOx) of diesel trucks, 10 trucks were run at temperatures of 40°F and 80°F. The emissions, in parts perbillion, are presented in the following table.Truck 40°F 80°F834.7 815.21753.2 765.2855.7 842.6901.2 797.1785.4 764.3862.9 819.5882.7 783.6740.3694.5748.0 772.9848.6 794.7NMTS 609235710Can you conclude that the mean emissions are higher at 40°F? Use a = 0.05.

38. Climate change 2016 Data collected from around the globe (including the sea ice data of Exercise 23) show that the earth is getting warmer. The generally accepted explanation relates climate change to an increase in atmospheric levels of carbon dioxide (CO.) because CO, is a greenhouse gas that traps the heat of the sun. A standard source of the mean annual CO, concentration in the atmosphere (parts per mil- lion) is measurements taken at the top of Mauna Loa in Hawaii (away from any local contaminants) and available at ftp://aftp.cmdl.noaa.gov/products/trends/ co2/co2_annmean_mlo.txt. Global temperature anomaly is the difference in mean global temperature relative to a base period of 1981 to 2010 in °C. It is available at www.ncdc.noaa. gov/cag/data-info/global.

"Radon: The Problem No One Wants to Face" is the title of an article appearing in Consumer Reports. Radon is a gas emitted from the ground that can collect in houses and buildings. At certain levels it can cause lung cancer. Radon concentrations are measured in picocuries per liter (pCi/L). A radon level of 4 pCi/L is considered "acceptable." Radon levels in a house vary from week to week. In one house, a sample of 8 weeks had the following readings for radon level (in pCi/L). 1.9 2.5 5.7 5.5 1.9 8.3 3.9 6.9 (a) Find the mean, median, and mode.

Mercury is a persistent and dispersive environmental contaminant found in many ecosystems around the world. When released as an industrial by-product, it often finds its way into aquatic systems where it can have deleterious effects on various avian and aquatic species. The accompanying data on blood mercury concentration (µg/g) for adult females near contaminated rivers in a state was read from a graph in an article. 0.20 0.23 0.24 0.30 0.35 0.41 0.54 0.57 1.43 1.70 1.82 2.20 2.24 3.08 3.24 (a) Determine the values of the sample mean and sample median. Hint: xi = 18.55. (Round your answers to four decimal places.) x== Explain why they are different. The sample mean and sample median are never equal.They aren't different since the data is symmetric. There is heavy negative skewness in the data.There are an odd number of data values.There is heavy positive skewness in the data. (b) Determine the value of the 10% trimmed mean.…

An article in Air and Waste ("Update on Ozone Trends in California's South Coast Air Basin," Vol. 43, 1993) studied the ozone levels on the South Coast air basin of California for the years 1976-1991. The author believes that the number of days that the ozone exceeds 0.20 parts per million depends on the seasonal meteorological index (the seasonal average 850 millibar temperature). The data follow: Year Days Index 16.3 1976 91 1977 105 17.1 1978 106 18.2 1979 108 18.1 1980 88 17.2 1981 91 18.2 1982 58 16.0 1983 82 17.2 Round your answers to 2 decimal places.
