1.Drinking water has become an important concern among people. The quality of drinking water must be monitored as often as possible during the day for possible contamination. Another variable of concern is the pH level, which measures the alkalinity or the acidity of the water. A pH below 7.0 is acidic while a pH above 7.0 is alkaline. A pH of 7.0 is neutral. A water-treatment plant has a target pH of 8.0. Based on 16 random water samples, the mean and standard deviation were found to be 7.6 and 0.4, respectively. Does the sample mean provide enough evidence that it differs significantly from the target mean? Use = 0.05.

2.The owner of a factory that sells a particular bottled fruit juice claims that the average capacity of their product is 250 ml. To test the claim, a consumer group gets a sample of 100 such bottles, calculates the capacity of each bottle, and then finds the mean capacity to be 248 ml. The standard deviation s is 5 ml. Is the claim true?
