The heights of women aged 20 – 29 in the United States are approximately Normal with mean 64.2 inches and standard deviation 2.8
Alenkinab [10]

Answer:

a) 0.64

b) -1.13      

Step-by-step explanation:

We are given the following information in the question:

Women:

Mean, μ = 64.2 inches

Standard Deviation, σ = 2.8 inches

We are given that the distribution of heights of women is a bell shaped distribution that is a normal distribution.

Men:

Mean, μ = 69.4 inches

Standard Deviation, σ = 3.0 inches

We are given that the distribution of heights of men is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

5.5 feet = 66 inches

a)  z‑score for a woman 5.5 feet tall

x = 66\\\\\Rightqrrow z = \displaystyle\frac{66 - 64.2}{2.8} = 0.64

b) z‑score for a man 5.5 feet tall

x = 66\\\\\Rightqrrow z = \displaystyle\frac{66 - 69.4}{3.0} = -1.13

Sarah notices the number of ounces of water drunk varies directly with how many glasses she drinks. On Thursday she drank 6 glas
IRISSAK [1]
Her goal is to drink 12 glasses of water, because the question tells us that every glass of water has the same amount of ounces. If she drank 6 glasses and there's 66 ounces in total, all we have to do to get the amount of ounces per glass is divide 66 by 6 to get 11. Therefore, we know that the total amount of ounces divided by the amount of ounces per glass is the amount of glasses, and 132 divided by 11 is 12.
