Researchers interested in lead exposure due to car exhaust sampled the blood of 52 randomly selected police officers who were (as part of their job) subjected to constant inhalation of gas fumes while working traffic enforcement. All chosen police officers worked in urban areas. The mean blood lead concentration was 124.32 units, with a standard deviation of 37.74 units. A previous study of police officers who worked in a suburb found a mean blood lead concentration of 35 units. (a)...

A local winery bottles thousands of bottles of wine per season. The winery has a machine that automatically dispenses the amount of wine per bottle before aging. Each season the wine maker randomly samples 50 bottles of wine to ensure the amount of wine per bottle is 750 ml. If there is evidence that the amount is different than (less or more than) 750 ml then the winery will need to evaluate the machine and perhaps rebottle or consider selling...

Suppose a batch of metal shafts produced in a manufacturing company have a standard deviation of 1.5 and a mean diameter of 205 inches. If 79 shafts are sampled at random from the batch, what is the probability that the mean diameter of the sample shafts would differ from the population mean by more than 0.3 inches?

In a lake pollution study, the concentration of lead in the upper sedimentary layer of a lake bottom is measured from 25 sediment samples of 1000 cubic centimeters each. The sample mean and the sample standard deviation of the measurements are found to be .38 and 0.06, respectively. (a) Compute a 99% confidence interval for the mean concentration of lead per 1000 cubic centimeters of sediment in the lake bottom. (b) State any assumption in (a) that is needed about...

A large university is interested in learning about the average time it takes students to drive to campus. The university sampled 238 students and asked each to provide the amount of time they spent traveling to campus. This variable, travel time, was then used conduct a test of hypothesis. The goal was to determine if the average travel time of all the university’s students differed from 20 minutes. Suppose the sample mean and sample standard deviation were calculated to be...

A soft drink company has recently received customer complaints about its one-liter-sized soft drink products. Customers have been claiming that the one-liter-sized products contain less than one liter of soft drink. The company has decided to investigate the problem. According to the company records, when there is no malfunctioning in the beverage dispensing unit, the bottles contain 1.02 liters of beverage on average, with a standard deviation of 0.16 liters. A sample of 60 bottles has been taken to be...
