Let x be the weight of a fawn in kilograms. The Standard Normal Distribution 68% of area 95% of area 99.7% of area Convert the following x intervals to z intervals. (Round your answers to two decimal places.) (a) x

Explanation / Answer

z = (X - mean)/sd
X mean + z* sd
you have not provided mean and sd , but it can be calculated from answer from a) -c) part

30 = mean + 1.23 * sd
19 = mean - 2.43 * sd

solving mean = 26.3 , sd = 3

d)
z = -2.17
x = mean + z * sd
= 26.3 -2.17 *3
= 19.79

e)
z = 1.28
X = 26.3 + 1.28 *3
= 30.14

f)
z1 = -1.99 ,z2 = 1.44
x1 = 26.3 -1.99 *3 = 20.33
x2 = 26.3 +1.44 *3 = 30.62
