Answer:

Mean = $\sum x P(x) = 36.86$

Standard deviation = $\sum x^2P(X)=1360.9$

Step-by-step explanation:

x P(x) $x \times P(x)$ $x^2 \times P(x)$

33 0.02 0.66 21.78

34 0.06 2.04 69.36

35 0.1 3.5 122.5

36 0.2 7.2 259.2

37 0.24 8.88 328.56

38 0.26 9.88 375.44

39 0.1 3.9 152.1

40 0.02 0.8 32

1 36.86 1360.9

We are supposed to find mean and standard deviation

Mean = $\sum x P(x) = 36.86$

Standard deviation = $\sum x^2P(X)=1360.9$

Choose the ratio below that is equivalent to the greatest fraction

Mumz [18]

Ratio 5:2 as fraction should be 5/2

as you know 5/2 = 2.5

This is the biggest compared to 9/5, 8/5 and 2/7

9/5 < 2
8/5 <2
2/7 < 1

so 5/2 is greatest
