Question

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
The time it takes for climbers to reach the highest point of a mountain is normally distributed with a standard deviation of 0.75 hours. A sample of 35 people is drawn randomly from the population.

The standard error of the mean of the sample is (blank)
hours. (Round off your answer to the nearest hundredth.)

Answer 1

Answer: 0.13

Step-by-step explanation:

The standard error of the mean is calculated using the formula

standard deviation / square root of the sample size.

So we take the standard deviation of 0.75 hours and divide by the square root of 35. Therefore, the answer is 0.13.
