Transcribed Image Text:Interpret the results. Select the correct choice below and fill in the answer box(es) to complete your choice.
(Round to three decimal place as needed.)
A. With 10% confidence, you can say that the population standard deviation is less than
inches.
B. With 90% confidence, you can say that the population standard deviation is between
and
inches.
O C. With 90% confidence, you can say that the population standard deviation is greater than
inches.
