Answer:
"Teens and Distracted Driving: Texting, Talking and Other Uses of the Cell Phone Behind the Wheel"
a. The inference made involves estimation. The question provided that the statements were made on the basis of the resulting data and not on the basis of some hypothesis testing.
This implies that some statistics were calculated from sample data to approximate the population parameter, as shown in the statements. The statements were not an attempt to establish the statistical significance of some claims.
b. The population of interest is American teenagers between 12-17.
Step-by-step explanation:
An inference from data is a statistical estimation by which some statistics are calculated based on the sample data of 800 teens between the ages of 12 and 17. The statistics serve as an approximation to the population parameter.
Inference based on hypothesis testing establishes if a claim has statistical significance by providing statistical evidence in favor of the claim or against it.
70dB is represented by 100cars in 60sec. Therefore if the number of cats is reduced by 3/4 in the same amount of time(60s), then the decibel level will reduce by 3/4 also. So 70dB * .25= 17.5dB
Answer:
#1: -1.5, -0.5, 1/2, 1.5
#2: -3, -1, 1.2, 2.3
Step-by-step explanation:
#1
First we have to figure out the correct order before we plot.
Find the biggest number:
looking at the number the biggest would be 1.5
Find the smallest number:
Looking at the number the smallest would be -1.5
Now that we have that we can easily figure out the rest...
(Going from least to greatest; like on a number line)
-1.5, -0.5, 1/2, 1.5 (That is how you will place the first one)
#2
(Use the steps from above to find the answer)
Biggest: 2.3
Smallest: -3
Order: -3, -1, 1.2, 2.3 (Placing on number line use that order)
Hope this helps :)
Answer:
The correct answer is C, as growth on stock E is bigger from the growth of stock B
Step-by-step explanation:
In order to resolve this problem, we must have in mind that the negative numbers are smaller when they are more distant from 0, and that positive numbers are bigger when they are more distant from 0. So, the biggest number of growth is the one that is more distant from 0.
The correct answer is C, as growth on stock E is bigger from the growth of stock B.
1.5 cleaner / 12 cups of water
or
1.5 cleaner : 12 cups of water
to reduce this ratio of 1.5:12, we need to divide both by the same number
1.5 divided by 1.5 is 1
12 divided by 1.5 is 8
So the ratio of cleaner to water is 1:8 in its simplest form or 1 part cleaner to 8 parts water.
Hope this helps!! :)
