Use the given data to find the minimum sample size required to estimate a population proportion or percentage. Margin of error:
lisabon 2012 [21]

Answer: 191

Step-by-step explanation:

Formula to find the minimum sample size required to estimate a population proportion or percentage:

n= \hat{p}(1-\hat{p})(\dfrac{z^*}{E})^2

, where \hat{p} = proportion estimated by prior study.

E= Margin of error.

z* = Critical z-value.

Given : Confidence level = 95%

Critical value for 95% confidence = z*=1.96

\hat{p}=\ 42\%=0.42

E= 7%= 0.07

Then, n= 0.42(1-0.42)(\dfrac{1.96}{0.07})^2

n= 0.42(0.58)(28)^2

n= 0.2436(784)=190.9824approx191

Hence, the minimum sample size required=191

Shawna is making smoothies. The recipe calls for two parts yogurt to three parts blueberry. Shawna wants to make 10 cups of smoo
BaLLatris [955]

Answer:

Shawna needs a mix of 4 cups of yoghurt and 6 cups of blueberries

Step-by-step explanation:

Here, we want to know the number of cups of yoghurt and smoothies Shawna needs to make;

We have 2 parts yoghurt and 3 parts blueberry, so we can say we have a ratio of 2:3

The total number of cups to be made is 10

So the number of cups of yoghurt will be;

2/(2+3) * 10

= 2/5 * 10 = 4 cups

The number of cups of blueberry would be;

3/5 * 10 = 6 cups

So a mix of 4 cups of yoghurt and 6 cups of blueberries is needed by Shawna
