Question 1 is no doubt B, because Johnny only asked the students in his science class, not the entire school's population. As for question 2, If you could give me a picture of the actual graph, that would be fantastic. Until then, i don't think I can answer Q2 properly.

Question 1 is D.<em> </em>

It's not clear that the science class is a good sample of the school as a whole. It may be an elective or for a particular grade, making it a biased sample.

For Question 2 I'll try to create the histogram from your description.

N TOP BOTTOM

9 3 3

10 5 4

11 2 3

If that's accurate the BOTTOM, B, group has longer arms, due to a single person measuring 11 instead of 10.

Neither B or D is really a good answer making me think I transcribed the table incorrectly. I'd guess D

Seth's mother brought home 3/4 of a chocolate cake and 1/2 of a vanilla cake that was left from a party at her work. Seth ate 1/
Oduvanchick [21]

Answer:

1/4 of the cake.

Step-by-step explanation:

Since he ate 1/3 of 3/4 of the chocolate cake, we will need to multiply fractions to solve this.

\frac{3}{4} * \frac{1}{3} =  \frac{3}{12}  = \frac{1}{4}

Therefore, he ate 1/4 of the entire cake.

Is there a difference in the amount of airborne bacteria between carpeted and uncarpeted rooms? In an experiment, seven rooms we
Annette [7]

Answer:

C. There isn't much evidence to support a conclusion that the presence of carpet is associated with an increase or decrease in the mean bacterial concentration of air.

Step-by-step explanation:

A. There are outliers in these data, so we can't rely on the two-sample t test.

There are no outliers, as the seven rooms for both sample have similar size and function.

B. This test is unreliable because the populations we're sampling from are heavily skewed.

We don't know if the populations are heavily skewed, but this effect should be appeased by the sampling.

C. There isn't much evidence to support a conclusion that the presence of carpet is associated with an increase or decrease in the mean bacterial concentration of air.

Correct conclusion, as the P-value is surely greater than the significance level (usually 0.10 at most).

D. There is fairly strong evidence to support a conclusion that the presence of carpet is associated with an increase or decrease in the mean bacterial concentration of air.

There is no evidence as the P-value is greater than the significance level.

Lana71 [14]
11 cups of strawberries ... 6 pitchers of juice
x cups of strawberries = ? ... 1 pitcher of juice

If you would like to know what is the number of cups of strawberries in each pitcher, you can calculate this using the following steps:

11 * 1 = 6 * x
11 = 6 * x      /6
x = 11/6
x = 1 5/6 cups of strawberries

Result: You will need 1 5/6 cups of strawberries in each pitcher.
