Suppose you are conducting a study about how the average US worker spends time over the course of a workday. You are interested

in how much time workers spend per day on personal calls, emails, and social networking websites, as well as how much time they spend socializing with coworkers versus actually working.
The most recent census provides data for the entire population Of U.S. workers on variables such as travel time to work, time spent at work, and break time at work. The census, however, does not include data on the variables you are interested in, so you obtain a random sample of 82 full-time workers in the United States and ask about personal calls, e-mails, and so forth. You are curious about how your sample compares with the census, so you also ask the workers the same questions about work that are asked in the census.

Suppose the mean break time per day from the most recent census is 29.6 minutes, with a standard deviation of 16.0 minutes. Your sample of 82 U.S. workers provides a mean break time per day of 31.9 minutes with a sample standard deviation of 22.4 minutes.

Organize this information by completing the following table.

μ = _________ M= __________
σ= _________ s= ___________
σM = _______ sM = _________

What is 1 1/2 subtracted from the sum of 4 2/3 and 5 2/5
Nezavi [6.7K]
Hi there!

First, we need to add 4 2/3 and 5 2/5.

We should begin with converting the fractions into improper fractions.
4 2/3 + 5 2/5
= 14/3 + 27/5

Now, we find the common denominator.
= 70/15 + 71/15

We can add:
= 141/15

And simplify.
= 9 2/5

Finally, we subtract 1 1/2 from 9 2/5.
9 2/5 - 1 1/2
= 47/5 - 3/2
= 94/10 - 15/10
= 79/10
= 7 9/10

Your answer is 7 9/10.

Hope this helps!

What is the volume of a rectangular prism that has a length, width, and height of 12 m, 14 m, and 23 m, respectively?
AveGali [126]
Find the volume with this formula
v = l × w × h

Given from the question
l = 12 m
w = 14 m
h = 23 m

Plug in the numbers into the formula
v = l × w × h
v = 12 × 14 × 23
v = 3,864

The volume of the rectangular prism is 3,864 m³
