Find an estimate of the sample size needed to obtain the specified margin of error for the 95% confidence interval of a population mean.

Past studies suggest that a population standard deviation of 42 mmHg is reasonable. Estimate the minimum sample size needed to estimate the population mean with the stated accuracy.
