There are twenty classes at each of two middle schools. The number of students in each class at each school is shown in the dot
tatuchka [14]

Answer:

There are about 2 more students in each class at Oak Middle School than at Poplar Middle School.

Step-by-step explanation:

The rest of the question is the attached figure.

It is required to compare between the mean number of students for the data in the plots.

The mean is sum of all data divided by the number of data.

The data set of Poplar Middle School:

20,20,20,21,21,21,21,21,22,22,22,22,22,22,22,23,23,23,23,24

So, The mean = 435/20 = 21.75

<u>The data set of Oak Middle School:</u>

20,21,21,22,22,23,23,23,23,24,24,24,25,25,26,26,27,27,28,29

So, The mean = 483/20 = 24.15

The difference in mean = 24.15 - 21.75 = 2.4

So, the correct statement is:

There are about 2 more students in each class at Oak Middle School than at Poplar Middle School.

Samples of size n = 600 are taken from a telephone survey, and the mean age is taken for each sample. What is the distribution o
Nonamiya [84]
The answer in B. For complicated statistics reasons the Central Limit Theorem states that, for sample sizes of above 25 (or 30 depending on the text!), the distribution of sample means is approximately normal regardless of the distribution of the parent distribution

what is the equation of a line that passes through the points (0,5) and (4,8)? write the answer in slope-intercept form.
Sergio039 [100]

Answer:

<h2>y = 3/4x + 5</h2>

Step-by-step explanation:

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept → (0, b)

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (4, 8) and (0, 5) → b = 5.

Calculate the slope:

m=\dfrac{5-8}{0-4}=\dfrac{-3}{-4}=\dfrac{3}{4}

Therefore we have the equation of the line:

y=\dfrac{3}{4}x+5
