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 )
Answer:
It prints "hi" only one time.
Explanation:
It will print the result depending on the if statements. If you look at the if statements, you will see that no matter you enter it is going to be either true for the first if statement or for the second if statement.
Let's say you entered 1 for x and 0 for y, first if statement will print hi, but the second one will not print because x is not smaller or greater than 0.
Let's say you entered 0 for x and 6 for y, second if statement will print hi, but the first one will not print because x is not greater than 0.
