Answer:
Options B,C and E are correct choices.
Step-by-step explanation:
We are asked to find correct answers for the given box and whisker plots.
Let us our options one by one.
A. This option is false as lowest value for children's cereals is 30 and highest value for adults is 35.
B. This option is correct. We can see our upper value for combined range will be 60 and lower value will be 5 and range is upper value- lower value.

C. Since we know that we can find spread of data by its range.


So option C is correct indeed.
D. This options is false because for adults mean and median are different while for children mean and median are same.
E. We can see that median for children's cereals is 45 and it is about 12 for adults.
We can see that
. So median amount of sugar in children's cereals is 3 times as much as the median amount of sugar in adult's cereals.
Therefore, options B,C and E are correct choices.
Answer:
A & B
Step-by-step explanation:
15/20 is not equal
6/8 is not equal
30/50 is equal
12/20 is equal
Answer:False
Step-by-step explanation:
4: 4, 8, 12
6: 6, 12
The least common denominator is 12.
Answer: a) -0.2252, b) 0.8219
Step-by-step explanation:
Since we have given that
Sample size n = 100
Probability that candies are blue = p= 0.26
Probability that company claims that it is blue candy = P = 0.27
So, Q = 1-P= 1-0.27 = 0.73
So, Null hypothesis : 
Alternate hypothesis : 
So, the test statistic would be

Since α = 0.05
So, critical value of z = 1.96
p-value = P(Z>Z(calculated)
Using the excel function , we get that

Hence, a) -0.2252, b) 0.8219
Answer:
This question is solved in detail below. Please refer to the attachment for better understanding of an Ellipse.
Step-by-step explanation:
In this question, there is a spelling mistake. This is vertices not verticles.
So, I have attached a diagram of an ellipse in which it is clearly mentioned where are the vertices of an ellipse.
Vertices of an Ellipse: There are two axes in any ellipse, one is called major axis and other is called minor axis. Where, minor is the shorter axis and major axis is the longer one. The places or points where major axis and minor axis ends are called the vertices of an ellipse. Please refer to the attachment for further clarification.
Equations of an ellipse in its standard form:
This is the case when major axis the longer one is on the x-axis centered at an origin.

This is the case when major axis the longer one is on the y-axis centered at an origin.
where major axis length = 2a
and minor axis length = 2b
