Answer:
188 weeks of data must be sampled.
Step-by-step explanation:
From the information given, we can deduce that:
The Margin of error is within = 200
The confidence interval = 95%
The level of significance = 1 - C.I
= 1 - 0.95
= 0.05
The standard deviation = 1400
The number of weeks the data must be sampled can be determined by using the formula for sample size which is:
n = 188.24
n ≅ 188
Thus, 188 weeks of data must be sampled.
Answer:
Sope = mx+b
Step-by-step explanation:
Slope=-5/4x
X^(3/5) = 1.84
x^(3/5) = (1.84)
Raise both sides of the equation to (5/3).
This is so that on the side with x, 3/5 * 5/3 = 1.
(x^3/5 )^5/3 = (1.84)^(5/3)
x^(3/5 * 5/3) = 1.84^(5/3)
x^1 = 1.84^(5/3)
x = 1.84^(5/3)
But remember we are solving for x^2.
x = 1.84^(5/3)
x^2 = (1.84^(5/3))^2
x^2 = 1.84^(5/3 *2 )
x^2 = 1.84^(10/3)
Use a calculator here.
x^2 = 1.84^(10/3) ≈ 7.63
Option A.
Cheers!
