QUESTION 3 Toyota provides an option of a sunroof and side airbag package for its Corolla model. This package costs $1400. Assum

Orlov [11]

Answer:

n=601

Step-by-step explanation:

Formula used:

$n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}$

Solution:

$n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}$

Where,

$\frac{\alpha }{2}=0.025$

As there is no previous estimate for p

Then, p=0.5

Here on using the table

$z(\frac{\alpha }{2}) =1.959963985$

Also,

E=0.04

p=0.5

Thus,

n=600.2279407

On approximating the value,

n=601
