Write 3/16 as a percent A.) 6.25% B.) 18.75 C.) 31.6 D.) 1875%

Hello! Just by lookiing at the answer choices, we can eliminate D, because that percentage is just too big. What you would need to do is divide 3 by 16. 3/16 is 0.1875. Multiply that by 100 to get 18.75, which will be the percent, because percents are parts of 100. There. 3/16 is 18.75%. The answer is B: 18.75%.

adelina 88 [10]

Answer:

246

Step-by-step explanation:

In the statment is defined our Values.

First que have a 95% Confidence interval

That is exactly in a Standar normal distribution table equal to Z Score = 1.96

The proportion $\hat{p}$ = 0.20

And we can and Margin Error (ME) equal to 0.05

Using the formula for the Sample Size (N) through Proportion we have,

$N= \frac{Z_{score}^2*\hat{p}*(1-\hat{p})} {ME^2}$

$N= \frac{1.96^2* 0.20 * (1-0.20)}{0.05^2}$

$N= 245.86$ or 246

Alternative hypothesis: $p< 0.29$
