Answers
Step-by-step explanation:
1) 3/5 + 2/5 = 5/5 or 1
2) to do this problem you need to make the denominators the same
(2/3)4 (1/4)3 8/12- 3/12. = 5/12
3)likewise here, you only have to change one denomimator
5 3/10 - (2/5)2
5 3/10 - 4/10
now to make this easiee for myself I prefer to make it a mixed number so 5(10)+ 3 = 53/10
53/10 - 4/10 = 49/10 then we convert this back to a mixed number and thus
5 3/10 - 2/5 = 4 9/10
4) 23 (1/12)2 - x = (3 5/8)3
23 2/24 - x = 3 15/24
- 3 15/24 +x = -3 15/24 + x
19 21/24 = x
simplify 19 7/8 liters sold

a. Set up the null hypothesis as a box model.
b. The SD of the box is:_______
c. Make the z-test.
d. What do you conclude?
Answers
Answer:
a. The H0 is number of correct guesses is 173
b. Standard Deviation of box is 0.3
c. z-test value is 7.70
d. The difference does not appear due to chances of Variation.
Step-by-step explanation:
The standard deviation is :
= 0.3
The standard deviation of the box is 0.3 approximately.
Z-score is
Z-score =
the value of z-score is 7.70.
A peak is where the frequency is lowest.
A peak is where the frequency is the highest.
A cluster is a group of bars, meaning the frequency is higher in these intervals.
A peak is a bar that is higher than the other bars around it.
Intervals on a histogram where there are no bars mean the frequency is 0.
If the graph is symmetrical, the data is clustered toward the right side.
If the graph is symmetrical, the data is evenly distributed.

The correct statement about histogram is as follows;
A peak is where the frequency is the highest.
A cluster is a group of bars, meaning the frequency is higher in these intervals.
A peak is a bar that is higher than the other bars around it.
Intervals on a histogram where there are no bars mean the frequency is 0.
If the graph is symmetrical, the data is evenly distributed.
We have to determine, which descriptions of a histogram are true?
According to the question,
A histogram meaning can be stated as a graphical representation that condenses a data series into an easy interpretation of numerical data by grouping them into logical ranges of different heights which are also known as bins.
Characteristics of a Histogram are as follows;
A histogram is used to display continuous data in a categorical form.
In a histogram, there are no gaps between the bars, unlike a bar graph.
The width of the bins is equal.
A histogram is a type of representation of a data set where bars are used to represent the frequencies.
The area of these bars is said to be proportional to the frequency of the variable.
The peak of a histogram represents the highest value of frequency. Also, the peak is a bar that is higher than the other bars around it.
In a histogram intervals wherein bars cannot be seen would represent the frequency of that would zero.
Also, if the histogram is said to be symmetrical, then the data should be distributed evenly.
A peak is where the frequency is the highest.
A cluster is a group of bars, meaning the frequency is higher in these intervals.
