(21 Points ) 2. Savannah recorded the average rainfall amount, in inches, for two cities over the course of 6 months.
City A: {3, 2.5, 4, 4.5, 3, 1}
City B: {6, 4, 1.5, 3.5, 2, 4}

(a) What is the mean monthly rainfall amount for each city? Show your work.
City A:

City B:

answer:

City a=3 City b=3.5

Step-by-step explanation:

We have to put the data in numerical order. Once in order we must add all the numbers together them divide by the amount of data there is.

city a                                             city b

1                                                      6

2.5                                                  4

3                                                     1.5

3                                                     3.5

4                                                     2

+4.5                                              +4

=18  now we do 18/6 which =3   =21 now we do 21/6 which=3.5

City A's mean is 3                          City B's mean is 3.5

answer:

City A: {2, 3.5, 4, 4, 5, 5.5}

City B: {3.5, 4, 5, 5.5, 6, 6}

Mean is the average.

Average of City A = 4 (2+3.5+4+4+5+5.5 = 24 and 24/6 = 4)

Average of City B = 5 (3.5+4+5+5.5+6+6 = 30 and 30/6 = 5)

Mean Absolute Deviation

Mean Absolute Deviation of City A = 0.8

Mean Absolute Deviation of City B = 0.8

Median is the middle (after putting it in order least to greatest)

Median of City A = 4

Median of City B = 5.25 (5+5.5 = 10.5 and 10.5/2 =5.25)
