Calculate confidence interval for heartbeats per minutes

Reference no: EM13109762

We want to evaluate the average number of heartbeats per minutes for the certain population. Average number of heartbeats per minutes for the sample of 49 subjects was found to be 90. Suppose that these 49 patients constitute the random sample, and that population is normally distributed with standard deviation of 10. Calculate the 95% confidence interval for heartbeats per minutes in population.
