A) Five-number summary:
1. sample minimum
2. first quartile
3. median
4. third quartile
5. maximum
0) Order the data
State A: 4, 5, 6, 6, 7, 8, 9, 21, 25
State B: 10, 11, 12, 13, 14, 14, 15, 15, 16
1) Minimum:
State A: 4
State B: 10
2) Median: the middle of the sample
State A: 7
State B: 14
3) first quartle : the median of the first half:
State A: (5+6)/2 = 5.5
State B: (11+12)/2 = 11.5
4) third quartile: the median of the higher half
State A: (9+21) /2 = 15
State B: 15
5) Sample maximum:
State A: 25
State B: 16
6) Interquartile range: 3rd quartile - 1st quartile
State A: 15 - 5.5 = 9.5
State B: 15 - 11.5 = 4.5
B) Symmetry:
Distance to the median and the quartiles:
State A:
median - first quartile: 7 - 5.5 = 1.5
third quartile - median: 15 - 7 = 8
1.5 ≠ 8 => skewed (not symmetrical)
State B
median - first quartle : 14 - 11.5 = 2.5
third quartile - median: 15 -14 = 1
2.5 ≠ 1 => skewed
Answer:

Step-by-step explanation:
If we call "x" the number of call minutes used with this plan, the piecewise function used to describe it must represent;
a) a constant value of 29 for any x value smaller than or equal to 250
b) a line with positive slope of 0.35 for the region with x larger than 250. The mathematical representation of such increasing straight line, should be given by a line of slope m = 0.35, and containing the point (250, 29) which is the starting point for this right hand side portion of the domain:

So the function should look like:

or as shown above, in a more simplified form:

Answer:
6
Step-by-step explanation:
Answer:
12*3 is 36 and (2^2 + 2^3 ) is 12 so you have to get 12 to 36
Step-by-step explanation:
which is 12 *3 so 3
Answer:
h(1)=-13

Step-by-step explanation:
We are given that

We have to find the recursive formula of h(n).
Substitute n=1

n=2

n=3


:
:
:

Therefore, the recursive formula is given by
h(1)=-13
