STEP 1:
Add the number of total students
= 27+25+23
=75
STEP 2:
Find the percentage that 18 out of 75 students is.
18/75=x/100
cross multiply
(18*100)=(75*x)
1800=75x
divide both sides by 75
24%=x
Check:
75 * 24%= 18
Hope this helps! :) Good luck!

Answer:
Option B is right
Step-by-step explanation:
Given that there was a comparison test for two samples done. The differnce between the sample means does not fall within 95% confidence interval.
This means that there is 95% chance that there will be a significant difference between the two means.
Hence whenever we compare two samples, we find the mean difference, margin of error, and confidence interval 95%
Whenever the mean difference does not fall within the confidence interval, we find that the null hypothesis namely that the two means are equal cannot be accepted
Hence option B is true.
