Answer: a) (176.76,172.24), b) 0.976.
Step-by-step explanation:
Since we have given that
Mean height = 174.5 cm
Standard deviation = 6.9 cm
n = 50
we need to find the 98% confidence interval.
So, z = 2.326
(a) Construct a 98% confidence interval for the mean height of all college students.
(b) What can we assert with 98% confidence about the possible size of our error if we estimate the mean height of all college students to be 174.5 centime- ters?
Error would be
Hence, a) (176.76,172.24), b) 0.976.
Matter exists in three states; <em>solid, liquid and gas.</em>
The statement that corrects the error in his table is:
<em>D. The Solids column and the gas column should be switched because solids have a definite shape and volume and gases have no definite shape or volume.
</em>
<em />
<em />
Looking at the table, we have the following observations.
- <em>The solid column shows indefinite shape (because the particles fill in the container)</em>
- <em>The liquid column is properly cataloged</em>
- <em>The gas column shows a definite shape</em>
<em />
Solid has definite shape, while gas doesn't.
To make corrections, Marcus needs to switch the gas and the solid column.

Answer:
f(-3) =16
Step-by-step explanation:
f(x) = -5x + 1
f(-3) means let x=-3
Substituting x=-3 into the equation
f(-3) = -5 (-3) +1
Multiplying -5 and -3
f(-3) = 15+1
f(-3) =16
