When a virus is placed on a tobacco leaf, small lesions appear on the leaf. To compare the mean number of lesions produced by two different strains of virus, one strain is applied to half of each of 8 tobacco leaves, and the other strain is applied to the other half of each leaf. The strain that goes on the right half of the leaf is decided by a coin flip. The lesions that appear on each half are then counted. The data are given below:
Leaf Strian 1 Strain 2
1 31 18
2 20 17
3 18 14
4 17 11
5 9 10
6 8 7
7 10 5
8 7 6
What is the number of degrees of freedom associated with the apropriate t-test for testing to see if there is a difference between the mean number of lesions per leaf produced by the two strains?
a. 7.
b. 8.
c. 11.
d. 14.
e, 16.
Answer: a. 7
Step-by-step explanation: Degrees of Freedom is the number of values "allowed" to vary. For example:
In the experiment above, the sample has 8 tobacco leaves. Two strains will be applied to each leaf. The decision of which strain goes to the right or left is random. Each strain have 7 possible leaves it can be applied, because, for the last, the eight leaf, there is no choice.
Therefore, the degrees of freedom for this experiment is 7.
It can also be calculated as
df = n - 1
df = 8 - 1
df = 7

Summarize the data by filling in the frequency (to the nearest whole number), the relative frequency (3 decimals), and the percent frequency (1 decimal) values below.
Class Frequency Relative Frequency Percent Frequency 12-14 % 15-17 % 18-20 % 21-23 % 24-26 % (Total) %
Answer:
[tex]\begin{array}{cccc}{Class} & {Frequency} & {Relative Frequency} &{Percent\ Frequency}\ \\ {12-14} & {2} & {0.05} & {5\%}& {15-17} & {8} & {0.200}&{20\%}& {18-20} & {11} & {0.275} & {27.5\%}& {21-23} & {10} & {0.250} &{25\%}& {24-26} & {9} & {0.225}&{22.5\%} & {Total} & {40} & {1} & {100\%}\ \end{array}[/tex]
Step-by-step explanation:
Required
Complete the table.
First, group the data according to the class.
So, we have:
12-14:- 14 12 --- Frequency is 2
15 - 17:- 16 16 16 16 16 17 16 15 --- Frequency is 8
18 - 20:- 19 19 19 18 19 18 20 20 19 20 20 --- Frequency is 11
21 - 23:- 21 23 21 22 21 23 23 22 22 22 --- Frequency is 10
24 - 26:- 25 24 24 25 25 24 26 24 24 --- Frequency is 9
Next, fill the class frequency column
[tex]\begin{array}{cc}{Class} & {Frequency} \ \\ {12-14} & {2} & {15-17} & {8} & {18-20} & {11} & {21-23} & {10} & {24-26} & {9}\ \end{array}[/tex]
Relative frequency is calculated by dividing each frequency by the total frequency (40).
So, we have:
[tex]\begin{array}{ccc}{Class} & {Frequency} & {Relative Frequency}\ \\ {12-14} & {2} & {0.05} & {15-17} & {8} & {0.200}& {18-20} & {11} & {0.275} & {21-23} & {10} & {0.250} & {24-26} & {9} & {0.225}\ \end{array}[/tex]
The percent frequency is calculated by multiplying the relative frequency by 100%.
So, we have:
[tex]\begin{array}{cccc}{Class} & {Frequency} & {Relative Frequency} &{Percent\ Frequency}\ \\ {12-14} & {2} & {0.05} & {5\%}& {15-17} & {8} & {0.200}&{20\%}& {18-20} & {11} & {0.275} & {27.5\%}& {21-23} & {10} & {0.250} &{25\%}& {24-26} & {9} & {0.225}&{22.5\%} & {Total} & {40} & {1} & {100\%}\ \end{array}[/tex]

Convert into a mixed number.
9
Answer: [tex]1\frac{8}{9}[/tex]
Step-by-step explanation:
i'm assuming the fraction is [tex]\frac{17}{9}[/tex] correct? First you would have to find out how many times 9 can be multiplied to get as close to 17. Since it can only go one time, subtract 9 from 17, then add the one next to it which would get you the mixed number of [tex]1\frac{8}{9}[/tex]

There are 1,600 students at a university. 24% of students are sophomores, 20% are juniors, and 28% are seniors. How many students at the university are freshmen?
Answer:
448 freshman.
Step-by-step explanation:
How many students at the university are freshmen?
= (1 - (.24 + .2 + .28)) * 1600 = .28 * 1600 = 448 freshman.
A percentage is a way to describe a part of a whole. The number of students that are freshmen in the university is 448.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that 24% of students are sophomores, 20% are juniors, and 28% are seniors. Therefore, the percentage of the freshman in the university will be,
Percentage of freshman = 100% - 24% - 20% - 28%
= 100% - 72%
= 28%
Now, since there are a total of 1,600 students at the university. Therefore, the number of students that are freshmen in the university is,
Number of students = 28% of 1600
= (28/100) × 1600
= 448
Hence, the number of students that are freshmen in the university is 448.

Change x+2y=-6 into y=mx+b form
Answer:
y = -3 - x/2
Step-by-step explanation:
x + 2y = -6
You have to isolate y by minusing x on both sides
2y = -6 - x
Then you will isolate y by dividing both sides by 2
y = -3 - x/2
