To compare two products such as colas, a random sample is selected to taste two types of colas (A and B). Each selected subject
Nadya [2.5K]

Answer: The sample size would be needed = 385

Step-by-step explanation:

Let p be the prior population proportion.

Margin of error = E

When not estimate of p is given , the formula to calculate the minimum sample size <em>n</em> = 0.25(\dfrac{z^*}{E})^2 , where z* = critical value for given confidence interval.

Here z* for 95% confidence level is 1.96.

E=5%=0.05

Then n=0.25(\dfrac{1.96}{0.05})^2\approx385

Hence, the sample size would be needed = 385

Write 9.753 in words
vlabodo [156]
Hey there! :D

When you write out decimals, you use words that end with 'ths'. And you use the smallest digit's place to name the whole decimal. 

For example,

.1 = one-tenths  .25= twenty hundreths .345= three hundred and forty five thousandths

9.753= Nine and seven hundred fifty-three thousandths. 

I hope this helps!
