Answer #1

a)

Robert Juan , Linda

b)

Joel

c)

Jan , Susan

d)

For Robert

z value =1.18

z = (x - mean)/sigma

1.18 = (x - 160)/18

x = 1.18 * 18 + 160

x = 181

For Joel

z = (x - mean)/sigma

0 = (x - 160)/18

x = 0 * 18 + 160

x = 160

For Jan

z = (x - mean)/sigma

-0.66 = (x - 160)/18

x = -0.66 * 18 + 160

x = 148

For JUan

z = (x - mean)/sigma

1.80 = (x - 160)/18

x = 1.80 * 18 + 160

x = 192

For Susan

z = (x - mean)/sigma

-2 = (x - 160)/18

x = -2 * 18 + 160

x = 124

FOr Linda

z = (x - mean)/sigma

1.54 = (x - 160)/18

x = 1.54* 18 + 160

x = 188
