Answer 1

a)

Largest

Smallest

Mean

4.17

4.40

Standard Deviation

2.04

2.35

b)

Step 1: Square the number of standard deviations:

2.25

Step 2: Dividing 1 by answer to Step 1:

0.44

Step 3: Subtracting Step 2 from 1:

0.56

In view of the above calculation, it is noted that at least 56% of the observations lie within 1.5 standard deviations from the mean that is 75 * 0.56 = 42

c)

Largest

Smallest

Observations greater than x + 1.5s

7.2

7.9

Observations less than x - 1.5s

1.1

0.9

Count

64

65

Yes, they are much larger than what we found in part (b).

d)

Largest

Smallest

Count

Percentage of observations lie within 1.5 standard deviations of

the mean

85%

87%

It is noted that the dividend yields are normally distributed that is histogram is ...
