The second factor as it did not make travel easy at all
Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) =
=
= 0.0316
For x = 120, sample proportion(p) =
=
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z <
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
Images help tell a story where describing with words is either too lengthy, or practically impossible. For instance, you could have a map of a location and various arrows and other markings to describe movements of troops during a battle of the civil war. This is one example of many that you could have as an image on a website. Describing the troop movements with words only may be really difficult to do. Plus many people are visually oriented learners, so they benefit with images every now and then. Of course, it's best not to overdo things and overload the site with too many images. A nice balance is needed.
