Because there is an absolute value in this equation around the x and and you are only adding something to that, we know that this will always be positive. This eliminates all the choices except for [1,infinity), the third option.

Emily and Hunter tracked the average temperature in their city for the past 8 days. They recorded their temperature findings in

lions [1.4K]

Answer:

The mean absolute deviation = 3.5°F

Step-by-step explanation:

The sum of the given temperatures, ∑T, is found as follows;

∑T = 66°F + 57°F + 61°F + 65°F + 54°F + 62°F + 59°F + 56°F = 480°F

The number of days, n, over which the temperature was tracked = 8 days

Therefore, the mean, $\bar x$ , of the data set = ∑T/n = 480°F/8 = 60°F

The mean absolute deviation is given by the following formula;

$Mean \ absolute \ deviation = \frac{\sum \limits_{i = 1}^{n} \left | x_i - \bar x \right | }{n}$

Therefore, we have;

66 - 60 = $\left | 6\right |$ = 6

57 - 60 = $\left | -3\right |$ = 3

61 - 60 = $\left | 1\right |$ = 1

65 - 60 = $\left | 5\right |$ = 5

54 - 60 = $\left | -6\right |$ = 6

62 - 60 = $\left | 2\right |$ = 2

59 - 60 = $\left | -1\right |$ = 1

56 - 60 = $\left | -4\right |$ = 4

The mean absolute deviation is therefore;

The mean absolute deviation = (6 + 3 + 1 + 5 + 6 + 2 + 1 + 4)/8 = 3.5°F.
