Sagot :

Given:

Mean of the distribution = 190.3

Standard deviation = 19.8

Let's use the emperical rule to find the best value for the percentage of the area under the curve that is shaded.

Using the emperical rule, we can see that 68% of the area under the curve is shaded.

Let u, w and v represent the missing values.

Where u is the first, v is the second and w is the last missing value.

SInce is area under the curve is about 68%, that means it falls within the first standard deviation of the mean.

To find the missing value, apply the formula:

u = mean - standard deviation

v = mean

w = mean + standard deviation.

Hence, we have:

• u = 190.3 - 19.8 = 170.5

• The middle missing value is the mean since it is the highest point.

Therefore, the middle missing value is 190.3

• w = 190.3 + 19.8 = 210.1

Therefore, the missing values along the axis are:

170.5, 190.3, and 210.1

ANSWER:

Percentage of total shaded area = 68%

Missing values = 170.5, 190.3, and 210.1
