Assume that there are 100 students in the class.
(Working with numbers is easier than working with percentages).
There are 27 students who passed both tests, and 51 who passed only the first test.
The 27 students who passed both tests are included in the 51 who passed the first test.
We are asked "What percent of those who passed the first test also passed the second test?"
so we are asked "what percent of 51 is 27?"
let 51 be 100%
then 27 is
%=52.941%
Answer: 52.941%
What are the measurements of the triangular prism??
Answer:
A sample size of 28.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
In this question:
We need to find n for which s = 0.09, with p = 0.66. So
Rounding to the nearest whole number
A sample size of 28.
