Answer:
And we can calculate the p value with the following probability taking in count the alternative hypothesis:
And for this case using a significance level of we see that the p value is larger than the significance level so then we can conclude that we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true proportion is less than 0.02
Step-by-step explanation:
For this case we want to test the following system of hypothesis:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
(1)
And for this case we know that the statistic is given by:

The circumference of a circle with radius 
is 
. If the length of the radius is tripled, then the circumference becomes 
, which is just 3 times the original circle's circumference.
