Question 1043993: 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 $2.709 per gallon. A random sample of 35 gas stations is drawn from this population. What is the probability that the mean price for the sample was between $2.688 and $2.726 that week? Assume σ=$0.048
The probability that the sample mean was between $2.688 and $2.726 is? Round to four decimal places as needed
Interpret the results. Choose the correct answer below.
A.
About 98% of the population of 35 gas stations that week will have a mean price between $ 2.688 and $2.726.
B.
About 2% of the population of 35 gas stations that week will have a mean price between $ 2.688 and $2.726.
C.
About 2% of samples of 35 gas stations that week will have a mean price between $ 2.688 and $2.726.
D.
About 98% of samples of 35 gas stations that week will have a mean price between $ 2.688 and $2.726.
