A magazine published a study on the ammonia levels near the exit ramp of a highway tunnel. The data in the table below represent daily ammonia concentrations​ (in parts per​ million) on eight randomly selected days during the afternoon drive time. Complete parts a through c.
The chemical benzene is highly toxic to humans. However, it is used in the manufacture of many medicine dyes, leather, and coverings. Government regulations dictate that for any production process involving benzene, the water in the output of the process must not exceed 7,950 parts per million (ppm) of benzene. For a particular process of concern, the water sample was collected by a manufacturer 25 times randomly and the sample average x was 7960 ppm. It is known from historical data that the standard deviation o is 100 ppm. (a) What is the probability that the sample average in this experiment would exceed the government limit if the population mean is equal to the limit? (b) Is an observed x = 7960 in this experiment a firm evidence that the population mean for the process exceeds the government limit? Assume that the distribution of benzene concentration is normal.
In an agricultural experiment, the effects of two fertilizers on the production of oranges were measured. Fourteen randomly selected plots of land were treated with fertilizer A, and 10 randomly selected plots were treated with fertilizer B. The number of pounds of harvested fruit was measured from each plot. Following are the results.  Fertilizer A 473   507   526   479   477   468   516  467   519   523   483   540   518   488Fertilizer B 455   501   470   420   483   419   468   476   459   513Assume that the populations are approximately normal. Construct a 95% confidence interval for the difference between the mean yields for the two types of fertilizer. Interpret the results.
