Divide P by 4 to move 4 from one side of the equation to the other. s=P/4
Answer:
Step-by-step explanation:
Since the heights of women are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = heights of women.
µ = mean height
σ = standard deviation
From the information given,
µ = 65 inches
σ = 2.5 inches
The probability that a woman is taller than 70 inches is expressed as
P(x > 70) = 1 - P(x ≤ 70)
For x = 70
z = (70 - 65)/2.5 = 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.977
Therefore,
P(x > 70) = 1 - 0.977 = 0.023
The percent of women that are taller than a man of average height is 0.023 × 100 = 2.3℅
The answer is (3) (3,9.5)
