The resting heart rates for 80 women aged 46–55 in a simple random sample are normally distributed, with a mean of 71 beats per minute and a standard deviation of 6 beats per minute. assuming a 90% confidence level (90% confidence level = z-score of 1.645), what is the margin of error for the population mean? remember, the margin of error, me, can be determined using the formula mc014-1.jpg.

The margin of error is

Step-by-step explanation:

The margin of error represents the maximum expected difference between the true parameter and the estimated parameter.

Mathematically, it is calculated as,

where,

z = z score of the confidence interval,

σ = standard deviation,

n = sample size.

Putting the values,
