Astudy of six hundred adults found that the number of hours they spend on social networking sites each week is normally distributed with a mean of 17 hours. the population standard deviation is 6 hours. what is the margin of error for a 95% confidence interval?

The margin of error for a 95% confidence interval is 0.48.

Step-by-step explanation:

Since we have given that

N = 600

Mean = 17 hours

Standard deviation = 6 hours

We need to find the margin of error for a 95% confidence interval.

Margin of error is given by

Here, n = 600,

In 95% confidence interval z = 1.96

So, Margin of error would be

Hence, the margin of error for a 95% confidence interval is 0.48.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
