The box plots below show student grades on the most recent exam compared to overall grades in the class
which of the following best describes the information about the medians
1. the exam outlier at 60 makes the IQR narrower and the median higher
2. The class data is more evenly spread which pulls its medium down
3. The class median is lower than the exam median
4. The class Q3 is higher than the exam Q3
Answers
Answer:
3. The class median is lower than the exam median
Step-by-step explanation:
The median of the box plot is indicated by the vertical line that divides the box.
Thus, the Class median grade is about 80, while the Exam median grade is more than 80.
Comparing grades, this means that the class median is lower. than the exam median.
Therefore, "the class median is lower than the exam median" is the right information that describes the median.
Answer:
C- The class median is lower than the exam median

The inverse
Answers
Answer:
Step-by-step explanation:
find the inverse of the function y=9x+12
To find the inverse function, swap x and y, and solve the resulting equation for x.
If the initial function is not one-to-one, then there will be more than one inverse.
So, swap the variables: y=9x+12 becomes x=9y+12.
Now, solve the equation x=9y+12 for y.
[tex]f^{-1}[/tex](x) = (x-12)/9
y=(x−12)/9

write a word problem whose solution is $111
Answers
Answer:
Step-by-step explanation:
Word problem is a topic in mathematics that involves the interpretation of a given question with a mathematical expression so as to determine the value of the required variable.
Example: The price of a pencil is $10, and that of a ruler is $15.25. If Charles bought 5 pencils and 4 rulers, calculate the total amount of money spent.
price of a pencil = $10
price of a ruler = $15.25
Then,
cost of 5 pencils = $10 x 5
= $50
cost of 4 rulers = $15.25 x 4
= $61
Total amount of money spent by Charles = $50 + $61
= $111
The total amount of money spent by Charles is $111.

Carson's tablet has 2,000 videos. The play time for the videos is skewed to the right, with a mean of 135 seconds and a standard deviation of 25 seconds.
Part A: Can you accurately calculate the probability that the mean play time is more than 142 seconds for an SRS of 10 videos? Explain. (4 points)
Part B: If you take a random sample of 50 videos instead of 10, explain how the Central Limit Theorem allows you to find the probability that the mean play time is more than 142 seconds. Calculate this probability and show your work. (6 points)
Answers
Answer:
SEE BELOW
Step-by-step explanation:
A: Yes, it is 18.80%. Sample Mean= 135, Sample Standard deviation= 25/sq rt of 10 = 7.906, normalcdf(142, 999999, 135, 7.906) = .18796 × 100 = 18.796 = 18.80%
B: If we increase the sample size to 50, then, due to the Central Limit Therme, there should be less variation within the data (it should point to a more clear center). Sample Mean= 135, Sample Standard deviation= 25/sq rt of 50 = 3.535, normalcdf(142, 999999, 135, 3.535) = .02385 × 100 = 2.385 = 2.39%
The probability that the mean playtime is more than 142 seconds for an SRS of 10 videos is not accurately calculated and the probability that the mean playtime is more than 142 seconds is 0.0244.
Given :
The total number of videos on Carson's tablet is 2000.The mean is 135 seconds.The standard deviation is 25 seconds.A) The probability that the mean playtime is more than 142 seconds for an SRS of 10 videos is not accurately calculated because the sample size is too small due to which the central limit theorem cannot be applied.
B) According to the given data, the sample size is 50.
[tex]P(\bar{X}>142)=P\left(\dfrac{\bar{X}-\mu}{\dfrac{\sigma}{\sqrt{n} }}>\dfrac{142-\mu}{\dfrac{\sigma}{\sqrt{n} }}\right)[/tex]
[tex]P(\bar{X}>142)=P\left(Z>\dfrac{142-135}{\dfrac{25}{\sqrt{50} }}\right)[/tex]
[tex]P(\bar{X}>142)=P\left(Z>1.9798\right)[/tex]
Using the z table the above expression becomes:
[tex]P(\bar{X}>142)=0.0244[/tex]
