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:
Syntax is essentially the punctuation and grammar rules for a computer language.
Explanation:
Certain characters and words have special meanings and must appear in a particular order for the computer code to make any sense. A simple example from line 3 in Figure 2.2 is the piece of HTML code <head>.

Explanation:
We merge cells with the help of following methods.
<u>Method 1 </u>
- Highlight cells A1:D4
- click on the Home tab
- click on the <u>Merge and Center</u> icon in the Alignment group
1st method is not given in options of question.
<u>Method 2</u>
- Highlight cells A1:D4
- right-click and select Format Cells
- click Alignment
- choose the Merge cells option
<em>2nd method is matching with </em><em><u>option D. </u></em><em>So, Option D is the answer.</em>
