A frozen food company wants to estimate the mean sodium contents of all 12-0z vegetable dinner. The company wants to be \( 95 \% \) confident that the estimate will be within \( 0.49 \) milligram of the population mean. Assume the population standard deviation, \( \sigma \) is \( 3.6 \) milligrams. What is the minimum sample size \( n \) required? Always round up to the next higher integer to ensure that sample is large enough.
