Find the probability and interpret the results. If convenient, use technology to find the probability. During a certain week the mean price of gasoline was $2.708 per gallon. A random sample of 33 gas stations is drawn from this population. What is the probability that the mean price for the sample was between $2.697 and $2.721 that week? Assume σ =$ 0.044. The probability that the sample mean was between $2.697 and $2.721 is nothing. ____ (Round to four decimal places as needed.) Interpret the results. Choose the correct answer below. A. About 88% of the population of 33 gas stations that week will have a mean price between $2.697 and $2.721. B. About 12% of the population of 33 gas stations that week will have a mean price between $2.697 and $2.721. C. About 12% of samples of 33 gas stations that week will have a mean price between $2.697 and $2.721. D. About 88% of samples of 33 gas stations that week will have a mean price between $2.697 and $2.721.
