Answer:
n = 106
Step-by-step explanation:
Given
p = 0.5 and 1-p = q = 0.5
Margin of error = 0.08
Confidence level = 90%
Z score for 90% confidence level = 1.65
As we know -
Margin of error = z * Sqrt (pq/n)
Substituting the given value, we get –
0.08 = 1.65 * Sqrt (0.5*0.5/n)
Squaring both the sides and solving, we get
n = 1.65^2*0.5^2/0.08^2
n = 106.34 = 106
Answer:
Step-by-step explanation:
The product of two numbers is greater than one of the multiples if the other multiple is greater than 1.
a)
- 7/5 × 1/3 > 1/3 as 7/5 > 1 ⇒ yes
b)
- 3/4 × 2/9 < 2/9 as 3/4 < 1 ⇒ no
c)
- 4/3 × 2/9 > 2/9 as 4/3 > 1 ⇒ no
d)
- 5/7 × 1/3 < 1/3 as 5/7 < 1 ⇒ yes
15% ------- 75
100% ---- n
n=(100*75)/15=500
n=500
