A local convenience store in a large city closes each day at 10 P.M. The owner of the store is investigating whether mean sales will increase by at least $10 per day if the store remains open until 11 P.M. The owner asked the 41 members of a local civic group to estimate the amount of money they might spend during the extra hour. The sample mean was $11.50. The owner will conduct a one-sample t -test for a population mean. Have the conditions for inference been met? No, the sample was not chosen using a random method. Yes, all conditions have been met. No, the sample size is greater than 10 percent of the population. No, the distribution of the sample is not normal. No, the sample size is not large enough to assume normality of the sampling distribution.
