Find the gradient so (-5-3)/(2+1) =-8/3 input it in y=mx+c and also use the coordinates from the question

So it becomes
3=-8/3 (-1) + c
C=1/3
Y=-8/3 x+1/3

If one woman is selected find the probability that her height is less than 65 inch with a mean of 64.4 and standard deviations o

Debora [2.8K]

The probability of one woman to have height less than 64.4 in is 0.6293

<u>Explanation:</u>

Given:

Mean, μ = 64.4

Standard deviation, δ = 1.8

Probability that the height of the woman is less than 65 inch = ?

So,

P(x < 65) = 65 - μ / δ

$=\frac{65 - 64.4}{1.8}\\ \\= 0.33$

P (x < 65) = P( z < 0.33)

Finding the probability value from the z table we get:

P( z < 0.33) = 0.6293

Therefore, the probability of one woman to have height less than 64.4 in is 0.6293
