7. Make a box-and-whisker plot for the data. What is the upper quartile value? 56 32 48 52 51 53 48 38 35 42 40 46 54 50

In order to draw the Box-whisker plot, we need to rewrite the data in increasing order.

42 43 47 48 51 52 56 56 58 60 62 64 65 66

Mean of the data = (42 + 43 + 47 + 48 + 51 + 52 + 56 + 56 + 58 + 60 + 62 + 64

+ 65 + 66) ÷ 14

Mean of the data = 770 ÷ 14

Mean of the data = 55

Median = (56 + 56) ÷ 2

Median = 112 ÷ 2

Median = 56

Lowest value = 42

Highest value = 66

Range = Highest value - Highest value

Range = 66 - 42

Range = 24

Lower Quartile = 25% of the data

Lower Quartile = 48

Upper Quartile = 75% of the data

Upper Quartile = 62

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
