Ksivusya [100]

Answer: 0.2643

Step-by-step explanation:

Let p be the population proportion and \hat{p} be the sample proportion .

As per given question , we have

p=0.14\\\\ \hat{p}=0.13\\\\ n=478

z-score : \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}

z=\dfrac{0.13-0.14}{\sqrt{\dfrac{0.14(1-0.14)}{478}}}\\\\=-0.630087269176\approx-0.63

The required probability ( using z-table ):-

P(z

Hence, the probability that the proportion of books checked out in a sample of 478 books would be less than 13% = 0.2643

What is 0.083 repeting as a percentage?
Pachacha [2.7K]

0.083 as a percentage would be 8.3% with a horizontal bar on top of the three. This is to indicate that it is repeating. To find percentage when you have a decimal, multiply a decimal by 100. If it is a fraction, divide the numerator by the denominator and you get a decimal. Then multiply it by 100 to get the percent.
