san4es73 [151]

Answer:

95% confidence interval for the proportion of days that IBM stock increases.

(0.45814 , 0.58146)

Step-by-step explanation:

<u><em>Step:1</em></u>

Given that a stock market analyst notices that in a certain year, the price of IBM stock increased on 131 out of 252 trading days.

Given that the sample proportion

                      p^{-} = \frac{131}{252} = 0.5198

Level of significance = 0.05

Z₀.₀₅ = 1.96

<u><em>Step:2</em></u>

<u><em>95% confidence interval for the proportion of days that IBM stock increases.</em></u>

<u><em></em></u>(p^{-} - Z_{0.05} \frac{\sqrt{p(1-p)} }{\sqrt{n} } , p^{-} + Z_{0.05} \frac{\sqrt{p(1-p)} }{\sqrt{n} } )<u><em></em></u>

(0.5198 - 1.96(\sqrt{\frac{0.5198(1-0.5198)}{252} } , 0.5198 +1.96(\sqrt{\frac{0.5198(1-0.5198)}{252} })

(0.5198 -  0.06166 , 0.5198+0.06166)

(0.45814 , 0.58146)

<u><em>Final answer:-</em></u>

95% confidence interval for the proportion of days that IBM stock increases.

(0.45814 , 0.58146)

I don’t know how to do that
Alisiya [41]

Answer:

16

Step-by-step explanation:

Divide 64 by 8 to get 8. this is 1/8 of the books.

3/8 were non fiction, or 24

1/4 (2/8) were picture books, or 16

5/8 were non fiction or picture books, so ’the rest‘ of the chapter books is 3/8.

3/8 were chapter books, or 24.

add the amount of picture books and chapter books since they are the fictional texts.

16+24=40

subtract the amount of non fictional books from the amount of fictional books to get the sum.

40-24=16

What is the percent of 60 is 15
frutty [35]
To find the percent of 15 out of 60, you have to divide fifteen by sixty. 
Then, you multiply your answer by 100. (We do this because 100 percent is a exact amount. 100% of sixty is...well, sixty.)

15 / 60 = 0.25

Now, we can multiply 0.25 by 100:

0.25 * 100 = 25 (basically just moving the decimal two places to the right.)

Next, add a percent sign:

25%, is your answer. 

15 is 25% of 60.
