type the correct answer in the box. use numerals instead of words.\na track coach is gathering data on the stride length of each of her 52 team members when running a distance of 500 meters. the population mean is 62.95 inches with a standard deviation of 5.65 inches.\nwhat is the standard error of the sample mean? round your answer to the nearest hundredth.\nthe standard error of the sample mean is approximately \n\nreset next
Answer
Explanation:
Step1: Recall the formula
The formula for the standard error of the sample mean is $SE=\frac{\sigma}{\sqrt{n}}$, where $\sigma$ is the population standard - deviation and $n$ is the sample size.
Step2: Identify the values
We are given that $\sigma = 5.65$ inches and $n = 52$.
Step3: Calculate the standard error
$SE=\frac{5.65}{\sqrt{52}}\approx\frac{5.65}{7.2111}\approx0.78$
Answer:
$0.78$
