The owner of a gasoline service station wants to study gasoline purchases at his station. A random sample of 100 purchases results in a mean of Ý = 24 gallons. The population standard deviation (o) is known to be 10.2 gallons. 34. In the above description, the population standard deviation (o) is a. A statistic. b. A parameter. c. Neither a parameter nor a statistic. 200 nartw nsve ng to sonsrDR d. Unknown. noitudiua 35. In the above description, the sample mean (Y) is a. A statistic. b. A parameter. c. Neither a parameter nor a statistic. d. Unknown. 36. Suppose a 95% confidence interval for the mean purchase amount based on the sample data is 22 to 26 gallons. Based on this interval, how would you assess the statement: "Mean gas purchased at this station could be 23 gallons. The statement is reasonable. c.
