The formula to calculate the sample size for proportion is given by :_
Given : Significance level :
Critical value :
Margin of error :
The proportion of successes :
Now, the required sample size will be :-
Hence, the minimum required sample size = 323
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
3/4(8x + 20) - 4x > -11
x ==> ?
Step 02:
Inequality :
2x + 15 > -11
2x + 15 - 15 > -11 - 15
2x > - 26
2x / 2 > -26 / 2
x > - 13
The answer is:
x > -13
