It rained 18 days during the month of April what percentage of day did it not rain during the month of April

Answers

There are 30 days in April.

If 18 days had rain, it means 12 didn't.

18/30=x/100

Make sure both fractions can be made into fractions with a denominator of 100:

180/300=x/100

Divide 180/300 by 3:

60/100=x/100

This shows that the 18 days that did rain take up 60% of the whole month.

So then the remaining 12 days that didn't have rain must take up 40% of the month.

Solution:
40% of the days did not have rain during the month of April

We have to state the critical values for the same.

Z-critical:

T-critical:

The critical value for t depends upon the degree of freedom which is obtained from the sample size.

If n is the sample size, then , n - 1 is the degree of freedom.
