For a normal distribution, what percentage of values lies within two standard deviations of the mean?
a. 99.7%
b. 97%
c. 68%
d. 95%

Answer with explanation:

A Normal Distribution curve, which is a bell shaped curve,when a line is drawn at symmetry is drawn at the center, at that Point

→Mean =Median =Mode

→99.7% of the values lie between 3 standard deviation.

→95 % of the values lie between 2 standard deviation.

→68% of the data values lie between 1 standard deviation.

Drawn the Normal distribution curve for three different Percentages.

Option D: 95% →→→For a normal distribution, 95 percentage of values lies within two standard deviations of the mean.

it is b)

step-by-step explanation:

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m
