Transcribed Image Text:Highway TPH Data. Estimate the 95th percentile and its upper 95% confidence limit for the
highway TPH data below. Use the averages of the duplicated measurements for a
total of n = 30 observations.
Total petroleum hydrocarbons (TPH) in soil specimens collected
at 30 locations alongside a 44.8-mile stretch of major highway are given in the table
below. The length was divided into 29 segments of 1.5 miles and one segment of 1.3 miles.
The sampling order for these segments was randomized, as was the location within each
segment. Also, the sample collection was randomized with respect to the eastbound or
westbound lane of the roadway. There are duplicate measurements on three specimens
