Answer:
Correct the data she entered, and the software will adjust the graph.
Explanation:
Software is used to work with ease and efficiency. If there is any mistake during data entry, we can easily change that particular data and make it correct. There is no need to delete whole data and re enter the data again. As most of the software are user friendly and have the option to edit the information that already has been entered.
In mentioned case, Kiara should edit the data, that has been entered incorrect. After the correction of data, the graph will be automatically updated with new values and she found correct graph.
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 )
