Chi-square independence test.
What is Chi-square?A test that evaluates how well a model matches real observed data is the chi-square (2) statistic.
A chi-square statistic can only be calculated with data that is random, unprocessed, mutually exclusive, obtained from independent variables, and drawn from a sizable enough sample.
The outcomes of a fair coin toss, for instance, satisfy these requirements.
To test hypotheses, chi-square tests are frequently employed.
Given the size of the sample and the number of variables in the relationship, the chi-square statistic examines the size of any discrepancies between the expected results and the actual results.
According to the total number of variables and samples used in the experiment, degrees of freedom are utilized in these tests to assess whether a particular null hypothesis can be rejected. as well.
According to our question-
The independence of two variables, each of which is categorized into a variety of categories or attributes, is also tested using the chi square statistic.
When the cell probabilities rely on the unknown parameters, the goodness of fit test is relevant as long as the unknown parameters are substituted by their estimates and as long as one degree of freedom is subtracted for each estimated parameter.

What is a sample mean?An average of a group of data is called a sample mean.
A data set's central tendency, standard deviation, and variance can all be determined using the sample mean.
A population average can be determined using the sample mean, among other things.
Both the sample mean and sample median are helpful statistics for outlining a data set's core tendency.
The sample mean uses all of the data values because it is the arithmetic average.
Extreme values have no impact on the sample median, which simply uses one or two middle values.
So, we have the sample mean:
0 | 3 | 25 | 100 | 5,000
Now, in the given sample mean we can count that the number of values or the elements is 5.

Ciara Walker was earning $47,100 and received a 13% raise. Find her new annual earnings directly.
The annual earnings for Walker will be $53223.
How to calculate the percentage?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred.
In this case, Ciara Walker was earning $47,100 and received a 13% raise.
Her new annual earnings directly will be:
= $47100 + (13% × $47100)
= $47100 + $6123

Consider the given density curve. a uniform density curve is at startfraction 1 over 12 endfraction. what is the value of the median? 8 12 14 20
The median of the probability density curve is (c) 14
How to determine the median of the density curveFrom the question, we have the following parameters that can be used in our computation:
Initial position = 1/12
Suppose we have a set {x₁, ..., xₙ}
The median is the number at the middle.
The difference between a set and a density curve is that the density curve is continuous, so getting the exact middle value can be harder.
In the given graph, we have
Constant density curve that goes from 8 to 20.
Because it is constant, the median will just be equal to the mean,
So, the median is the average between the two extreme values.
The average of two numbers a and b is calculated as
(a + b)/2
So we have
Median = (a + b)/2
Substitute the known values in the above equation, so, we have the following representation
Median = (20 + 8)/2
Evaluate
Median = 14

11. Natalee wanted to write a function which shows a 40% increase in bacteria growth.
There were 100 bacteria to start. She wrote y = 100 (40)* but she felt that she was
wrong because her y-values were extremely high when she graphed it. Identify Natalee's
mistake, and write the actual function for this scenario.
Natalee's mistake is that she has written the function incorrectly. In her function, she has multiplied the starting number of bacteria, 100, by the growth rate, 40%, to get the final number of bacteria. However, this is not correct because a growth rate of 40% means that the number of bacteria increases by 40% of the starting number, not by 40 itself.
To write the correct function, we can use the fact that a growth rate of 40% means that the final number of bacteria is 1.4 times the starting number. Therefore, the correct function for this scenario is y = 1.4 * 100 = <<1.4*100=140>>140. This function shows that the number of bacteria increases to 140 after experiencing a 40% increase in growth.
Answer:
The actual function for this scenario would be:
y = 100 * 1.40
Step-by-step explanation:
Natalee's mistake was that she didn't add 1 to the value of the increase. When you multiply a number by 1 plus the percentage increase, you get the correct result. In this case, the correct function would be:
y = 100 * 1.40
This function will show a 40% increase in the number of bacteria, starting with 100 bacteria. When graphed, the y-values will not be extremely high.

The length of vertical segment XY can be found by subtracting the y-coordinate of point X from the y-coordinate of point Y.
In this case, the y-coordinate of point X is 13 and the y-coordinate of point Y is 7, so the length of vertical segment XY is

high school has 36 players on the football team. the summary of the players' weights is given in the box plot. how many players weigh between 169 and 194 pounds?
There are 8 players who weigh between 169 and 194 pounds.
To answer this question, we can look at the box plot to understand the distribution of weights on the football team. The box plot shows us the minimum, maximum, median, and quartiles of the team's weights. The left quartile is 169 pounds, and the right quartile is 194 pounds. This means that 25% of the team's players weigh between 169 and 194 pounds. Since the team has 36 players, 25% of 36 is 9. However, since we are looking at the number of players between 169 and 194 pounds, we need to subtract 1 since the right quartile of 194 pounds is included in the number of players. Thus, there are 8 players who weigh between 169 and 194 pounds.

Arthrogryposis, also called arthrogryposis multiplex congenita (AMC), is a term used to describe a variety of conditions involving multiple joint contractures (or stiffness).
Arthrogryposis is a general or descriptive term for the development of non progressive contractures affecting one or more areas of the body prior to birth (congenitally). A contracture is a condition in which the joint becomes permanently fixed in a bent (flexed) or straightened (extended) position, completely or partially restricting the movement of the affected joint. When congenital contractures occur only in one body area which means it is not referred to as arthrogryposis but rather as an isolated congenital contracture. The most common form of an isolated congenital contracture is clubfoot. When arthrogryposis affects two or more different areas in the body, it may be referred to as arthrogryposis multiplex congenita (AMC).

Eve knits scarves for her online store. This week she has already knitted 9 scarves. There are 2 days left in the work week. She set a goal for herself to knit at least 15 scarves and at the most 19 scarves this week. Eve wants to know how many scarves she should knit each day to meet her goal.
Which inequality represents the given situation?
• A. 15 ≤ 2x - 9 _> 19
• B. 15 ≤ 2x - 9 ≤ 19
• C. 15 ≤ 2x + 9 ≤ 19
• D. 15 _>2x+9 _>19
Answer: C. 15 ≤ 2x + 9 ≤ 19
Step-by-step explanation:
We know that her goal is to knit at least 12 scarves and, at the most, 19 scarves
So it has to be bigger or equal to 15 and smaller or equal to 19, so it can't be A or D.
We also know that she has already knitted 9, so our equation has to have a +9
So the answer is C. 15 ≤ 2x + 9 ≤ 19
