The given scatter plot has a positive correlation.

Given that, the scatter plot shows the number of hours worked and money spent on entertainment by every 24 students.

A scatter plot is a means to represent data in a graphical format. A simple scatter plot makes use of the coordinate axes to plot the points, based on their values. The following scatter plot excel data for age (of the child in years) and height (of the child in feet) can be represented as a scatter plot.

A positive correlation—when the correlation coefficient is greater than 0 signifies that both variables move in the same direction.

Given:

Length of the rectangular prism = 13 units.

Width of the rectangular prism = 6 units.

Height of the rectangular prism = 4 units.

To find:

The volume of the rectangular prism.

Solution:

We know that the volume of the rectangular prism is:

[tex]V=l\times b\times h[/tex]

Where, l is length, b is breadth or width and h is the height of the rectangular prism.

Putting [tex]l=13,b=6,h=4[/tex] in the above formula, we get

[tex]V=13\times 6\times 4[/tex]

[tex]V=312[/tex]

Therefore, the volume of the given rectangular prism is 312 cubic units.

Answer:

Criteria.

Step-by-step explanation:

A series of criteria is a set of parameters established by whoever seeks to interpret a certain information or quantity of concepts, by means of which a set of interpretive rules is established that should be equal to all the concepts to be analyzed. Thus, the criteria allow a set of data to be analyzed under the same parameters or information processing requirements.

Answer:

Step-by-step explanation:

             80% of 25 = 5

because 10% of 25 = 2.5

and then       10 x 8 = 80

so                2.5 x 8 = 20

                  25 - 20 = 5

therefore, the percentage change is 80%

Answer:

The null hypothesis is rejected.

Step-by-step explanation:

Assuming the proportions in each of the categories is the same which is 1/5 = 0.20.

H0: p1 = p2 = p3 = p4 = p5 = 0.2

Ha: H0 is not true.

The table is as below:

-----------------------------------------------------------------------------------------------

Total                                                                                     22.1428

The test statistic [tex]\chi^2[/tex] is 22.1421

The degree of freedom d is n-1=5-1 =4

The corresponding p-value from the chi-squared table is .000188.

As this value is less than the p-value for the H0 thus we reject the null hypothesis.

Answer:

We accept H₀. We don´t have enough evidence to support the difference between the two means

Step-by-step explanation:

Group 1 : Comunity College

Sample:

size  :   n₁  = 54

Sample mean    x₁  = 947

Sample standard deviation     s₁ = 254

Group 2 : Local University

Sample

size  :  n₂  =  66

Sample mean :  x₂  = 1011

Sample standard deviation    s₂  =  87

Significance level  α  = 0,05      α  =  5 %      CI = 95 %

Both samples are with n> 30 so we can use z table for the test

from z-table we find  z(c)  =  1,96

The problem statement establishes to run a hypothesis test to determine if the means are statistically the same  ( or different) then we use two-tail-test

Hypothesis Test

Null Hypothesis                        H₀             x₁   -  x₂  = 0 or    x₁  = x₂

Alternative hypothesis             Hₐ             x₁  -  x₂  ≠  0  or    x₁ ≠ x₂

To calculate

z(s)  =  (  x₁   -  x₂  ) / √ s₁²/n₁  + s₂²/n₂ )

z(s)  =  947  -  1011 / √  (254)²/54   +  (87)² / 66

z(s) = -  64  /√ 1194,74  +  114,68

z(s) =  - 64  / 36,185

z(s) =  - 1,77

Comparing modules of  |z(c)|  and |z(s)|

z(s) < z(c)

Then z(s) is in the acceptance region we accept H₀ . There is not enough evidence to support differences in the means of the two groups

Answer:

C. Not symmetric; not bell-shaped.

Step-by-step explanation:

In a symmetric data distribution, the shape on the left side is almost the same as the shape on the right side of the middle. In this type of data distribution, if different measure of centers are calculated (mean, median, and mode), they will have a similar figures that are close together. Symmetric distributions are bell-shaped.

On the other hand, if the data distribution is not symetric, it means the left and the right side of the distribution are not equal and do not have the same shape.

The data in the dot plot above is considered as NOT SYMMETRIC. Also, it is not bell-shaped.

Answer:

30 cm²

Step-by-step explanation:

To find the area of a triangle, multiply the base and the height, then, divide the product by 2.

In this case, the base is 6 and the height is 10.

6 x 10 = 60

The product is 60.

60 / 2 = 30

Therefore, the area of this triangle is 30 cm².

Answer:

30

Step-by-step explanation:

Formula for area of a triangle: [tex]A=\frac{bh}{2}[/tex]

where b = base length and h = height

The triangle shown has a base length of 6 cm and a height of 10 cm

Using this information we plug in the values into the formula

So...

[tex]A=\frac{10*6}{2} \\10*6=60 \\\frac{60}{2} =30[/tex]

Hence, the area of the triangle is 30 square centimeters.
