Step-by-step explanation:
X - Heights of women aged 20 to 29: X is N(64, 2.7)
Y - Heights of men aged 20 to 29: X is N(69.3, 2.8)
a) X=6'=72"
b) Y = 72"
c) 72' women can be taken as very tall but men moderately taller than average
d) Y<5'5" =65"
e) X>73"
Z>
Almost 0% can be taken
f) IQR =Q3-Q1

Answer:
-8,-7,-6,-5
Step-by-step explanation:
to start pick 4 variables lets say x, y, z, and a then remember that consecutive means one after another so x = x ,y = x + 1, z = x + 2, and a = x + 3. x + y + z + a = -26 so x + x + 1 + x + 2 + x + 3 = 26 then solve for x. finally go back and solve for the other variables.
