A medical researcher wishes to estimate the mean systolic blood pressure of heart surgery patients the day following surgery. She desires a margin of error of 2.2 mmHg. Past studies suggest that a population standard deviation of 41 mmHg is reasonable. Estimate the minimum sample size needed to estimate the population mean with the stated accuracy.
