Daniel looks at the prices of 5 guitars. The prices are $137, $159, $127, $188 and $680. These prices contain one extreme value
brilliants [131]

Answer:

D. Mean absolute deviation

Step-by-step explanation:

Median gives us : 159

Range gives us: 680 - 127 = 553

mean gives us :

127+137+159+188+680 = 1291

1291 / 5

= 258.2

MAD gives us the mean deviation (avg change from the mean):

mean

= 258.2

258.2 - 127 =131.2

258.2 - 137 =121.2

258.2 - 159 =99.2

258.2 - 188 =70.2

680 - 258.2

=421.8

Find the mean of the variances:

70.2+99.2+121.2+131.2+421.8 = 843.6

843.6 / 5

= 168.72

Mad = 258.2 +- 168.72

andriy [413]
To determine the number of days that an employee work in a week, we simply use dimensional analysis and multiplying the number of works per week with the number of weeks in total for a year. That is,
                         employee works = (5 days per week)(49 weeks per year) 
                                                    =245 days
