Answer:
The point estimate for 
is 8.5 hours.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation 
.
In this problem
We are working with a sample of 81 adults, so the point estimae of the mean is the mean number of weekly hours that U.S. adults use computers at home.
So, the point estimate for is 8.5 hours.
You could write this by going 63+42 or add 63 and 42
hope that's what you are looking for ;-)<span />
Answer:
The correct answer is Redbirds
P = 4/5 = 0.8
Answer: No
Step-by-step explanation: the ratio 3:6 reduces to one half
the ratio 6:3 reduces to 2 because division cannot be interchangeable
<span>The difference between constructing and drawing geometric figures:
</span>Drawing Geometric Figures refers to drafting, in which you are trying to create or sketch geometric figures using ruler, paper, etc.
While constructing geometric figure refers to constructing or building a geometric figure with the use of compass, graph paper, etc.
