deviation is $201.40. This creates a 90% confidence interval for the population mean of ($1334.50, $1428.20). Does it seem possible that the population mean could equal the sample mean exactly? Explain. Choose the correct answer below. A. It would be very unlikely because the margin of error is large enough that the odds of selecting an exact value is very B. It is possible because the sample mean is outside of the confidence interval. C. It is possible because the margin of error is small enough that the odds of selecting an exact value is not unlikely. O D. It is not possible because the sample mean is inside of the confidence interval.
