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:
The correct option for accessing the value in sarray[3] is : d) *(sptr+3)
Explanation:
a) *sptr[*3] is wrong option because its syntax is not right it will give errors.
b) *sptr+3 is also wrong option because it will add 3 to the value of sarray[0].
c) sptr+3 is wrong option because it will only access the address of sarray[3] not the value it contains.
d) *(sptr +3) is correct syntax for accessing value in sarray[3] by using pointer
This for loop will output:
0
2
4
The range(3) is all the integers between 0 inclusive and 3 exclusive. 0, 1, 2.
Every iterations through the for loop, we multiply the value of each number by 2 and print it to the console.
0 * 2 = 0
1 * 2 = 2
2 * 2 = 4
I hope this helps.
