Answer:
For school A: Minimum=6, Q₁=6.5, Median= 14, Q₃=16, Maximum=17, IQR=9.5
For school B: Minimum=5, Q₁=8, Median= 12, Q₃=15.5, Maximum=19, IQR=7.5
No, the box plots are not symmetric.
Step-by-step explanation:
Part A
The given data sets are
School A : 9,14,15,17,17,7,15,6,6
School B : 12,8,13,11,19,15,16,5,8
Arrange the data in ascending order.
School A : 6,6,7,9,14,15,15,17,17
School B : 5,8,8,11,12,13,15,16,19
Divide each data set in four equal parts.
School A : (6,6),(7,9),14,(15,15),(17,17)
School B : (5,8),(8,11),12,(13,15),(16,19)
For school A:
Minimum=6, Q₁=6.5, Median= 14, Q₃=16, Maximum=17
Interquartile range of the data is
For school B:
Minimum=5, Q₁=8, Median= 12, Q₃=15.5, Maximum=19
Interquartile range of the data is
Part B:
The box plots are not symmetric because the data values are different. Five number summary and IQR of both the data set are different.
Answer:
Step-by-step explanation:
Given information:
Maximum revenue = 42000
Minimum revenue = $25000
Time period = 12 months
We need to write a function that models the boutique's revenue during the year, where corresponds to the month.
.... (1)
where, A is amplitude, is period, C is phase shift and D is midline.
Substitute the value of A, B and D in equation (1).
..... (2)
In April, revenue of the store is $42000. So, the graph passes through the point (4,42000).
Divide both sides by 8500.
On comparing both sides we get
Substitute the value of C in equation (2).
Therefore, the required function is .
