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 ____
hours. (Round off your answer to the nearest hundredth.)

Answer 1

Answer:

0.13

Step-by-step explanation:

plato

Answer 2

The standard error of the mean of the sample approximating to the nearest hundredth gives; 0.127

How to find Standard Error of Mean?

We are given;

Standard deviation; σ = 0.75 hours

Sample size; n = 35

The formula for standard error of mean is;

SE = σ/√N

SE = 0.75/√35

SE = 0.126773

Approximating to the nearest hundredth gives;

SE ≈ 0.127
