The Anova assumptions are each population is normally distributed and the Types of Assumptions. Brookfield (1995) classifies assumptions into 3 categories: paradigmatic, prescriptive, and causal.
ANOVA assumes that the information is usually distributed. The ANOVA additionally assumes homogeneity of variance, because of this that that the variance many of the organizations must be about equal. ANOVA additionally assumes that the observations are impartial of every other. is primarily based totally on the idea that the populations must have the identical variance and they may be usually distributed.
Also, the pattern must be decided on randomly and independently from the populations. The handiest assumption that isn't required to apply ANOVA is c) All samples are of the identical size.The factorial ANOVA has a numerous assumptions that want to be fulfilled – (1) c programming language information of the based variable, (2) normality, (3) homoscedasticity, and (4) no multicollinearity.

Mariol buy 3 pound of cheee and 3 pound of auage for a total cot of $36. The auage cot $2. 00 le per pound than the cheee. What i the combined cot of 1 pound of cheee and 1 pound of auage?How much would Mariol pay for 4 pound of cheee and 1 pound of auage
Mariol pays $12 for a pound of cheese and a pound of sausage, and $42 for 4 pounds of cheese and 1 pound of sausage.
To solve this problem, we can apply simple algebra. Let's use the letter for the initial, C for a pound of cheese, and S for a pound of sausage.
3 C + 3 S = $36
If the sausage cost $2.00 per pound, so
3 C + 3 ($2) = $36
3 C + $6 = $36
To know the price for a pound of cheese, do as follow
3 C = $36 - $6
3 C = $30
1 C = $30 : 3 = $10
Thus, 1 pound of cheese and 1 pound of sausage would be $2 + $10 = $12
Moreover, if 4C + 1S = 4($10) + 1($2) = $40 + $2= $42

Or Find the miing number o that the equation ha infinitely many olution. – 3x–20= – 3x
For the equation -3x - 20 to have an infinite solution, it should be equal to -3x + 20 = -3x + 20, so the blank will be + 20
Given the data in the question,
Let the equation be - 3x + 20 = - 3x blank
These situations could be turned into producing an infinite number of solutions only if the lines are coincident and have the same y-intercept.
The quantities being coincident demonstrates the equality of the expressions printed on the left and right sides.
The lines with the same slopes are equal lines.
If the lines are making equal patterns, they will be giving infinite answers as output. As we can see in the result the equations are containing infinite solutions.
So, the missing blank will be = +20 to make the equation have infinite solutions.

Given,
Probability;-
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
Here,
The number of fortunate situations divided by the total number of coins would be the product between the probability of each occurrence and the likelihood of each event.
Therefore,
P(nickel) = 19/69
P(penny) = 17/68

percentage?
(round your answer to the nearest hundreths)
COOKIES
The sales tax percentage of cookie jar is 1.6% .
What is sales tax?Sales tax is a mandatory fee levied on the purchase of certain goods and services. The cost of goods and services rises as a result of sales tax.(sales tax / total cost of the item) x 100 = sales tax rate
To find the sales tax percentage:
To calculate the tax amount, subtract the net price from the gross price.Subtract the tax amount from the net price.Step 2's result is multiplied by 100. The outcome is the sales tax.Here given,
Total cost = $1.62
Gross price = $1.60
Tax amount = $1.62 - $1.60
= $0.02
By substracting the tax amount from total cost,
$1.62 - $0.02

how many ways are there to form a committee of 6 people from the department, if the number of men in the committee is less than the number of females in the committee? explain your answer.
there are 15 different ways to form a committee of 6 people from the department if the number of men in the committee is less than the number of females in the committee by combination.
There are 15 different ways to form a committee of 6 people from the department if the number of men in the committee is less than the number of females in the committee. This is because the number of possible combinations of 6 people with varying numbers of men and women is equal to the number of combinations of 6 people with 1 more female than male, plus the number of combinations of 6 people with 1 more male than female (which is equal to the number of combinations of 6 people with 1 more female than male).
Mathematically, this can be expressed as:
Number of combinations = (number of 6-person combinations with 1 more female than male) + (number of 6-person combinations with 1 more male than female)
Number of combinations = (6C4 x 5C2) + (6C5 x 5C1)
Number of combinations = 15

Why in this case would we expect the sample size to be small? (Mark all that might apply:) There limited amount of time that bat keepers maybe able to devote to this activity. The sample size doesn't have to be small: There are many bats in the wild We wouldnt want to unnecessarily stress the animals. There is limited number of bats in captivity:
When it comes to researching bats in captivity, we expect the sample size to be small for a few reasons.
Firstly, there may be a limited amount of time that bat keepers are able to devote to this activity due to other obligations. Secondly, we would not want to unnecessarily stress the animals by collecting too many samples. Lastly, there is a limited number of bats in captivity, so the sample size will be small.
On the other hand, there are many bats in the wild, which means that the sample size does not have to be small. Researchers can take advantage of this by collecting data from a larger sample size. However, researchers must be mindful of the impact that their research may have on the environment, and the stress that it may cause the animals.
In conclusion, the sample size for studying bats in captivity is likely to be small due to the limited amount of time that bat keepers can devote to this activity, the need to avoid unnecessarily stressing the animals, and the limited number of bats in captivity.
