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:
The appropriate z multiplier for 66% confidence interval is 0.95
Step-by-step explanation:
We are given the following in the question:
Confidence interval:
We have to make a 66% confidence interval for the proportion of voters.
Confidence level = 66%
Significance level =
Thus, the appropriate z multiplier for 66% confidence interval is 0.95
Area of circle 1 = πr²
Area of circle 1 = π (10)²
Area of circle 1 = 100π km²
Area of circle 2 = πr²
Area of circle 2 = π (5)²
Area of circle 2 = 25π km²

<u>Answer:</u>
The correct answer option is b. 560 units.
<u>Step-by-step explanation:</u>
We are given a prism with a base area of 40 square units and a height of 14 units.
We know the formula for the volume of the prism:
<em>the volume of a prism = Bh</em>
where <em>B</em> is the base area of the prism; and
<em>h</em> is the height of the prism.
Substituting the given values in the formula to get the volume:
Volume of prism = 40 x 14 = 560 units
