Answer:
Step-by-step explanation:
Given that the height in inches, of a randomly chosen American woman is a normal random variable with mean μ = 64 and variance 2 = 7.84.
X is N(64, 2.8)
Or Z = 
a) the probability that the height of a randomly chosen woman is between 59.8 and 68.2 inches.
b) 
c) For 4 women to be height 260 inches is equivalent to
4x will be normal with mean (64*4) and std dev (2.8*4)
4x is N(266, 11.2)
d) Z is N(0,1)
E(Z19) = 
since normal distribution is maximum only between 3 std deviations form the mean on either side.
Answer:
I think it's 2.3
Step-by-step explanation:
The difference of the medians is 14, and the range for both of the heights is 6. 14 divided by 6 is 2.3333
I think that the correct answer is B
Hope that helps.
<u>Answer:</u>
(B) $152.50
<u>Step-by-step explanation:</u>
Friday: 5 hours x $7.50 per hour = $37.50
Saturday: 6 hours x $7.50 per hour = $45
Sunday: 4 hours x $7.50 per hour = $30
$40 + $37.50 + $45 + $30 = $152.50
I would have <u>(B) $152.50</u> in total.
Hopefully this helps :3 sorry if wrong :( Plz mark brainiest if correct :D Your bootiful/handsome! Have a great day luv <3
