Explanation:
Left index finger: R, T, F, G, C, V
Right index finger: Y, U, H, J, B, N
Answer:
B. Graphs
Explanation:
Graphs are used to put certain things into categories. In this case Jamie has to enter different categories such as names, grades and the scored of the students. C and D don't make sense for this problem since they aren't actually what he is looking for. A is plausible but he needs it into a worksheet and labels aren't worksheets they are just labels. So B would be your answer. Also I took the quiz this is the correct answer.
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 )
