Answer: a) Required minimum sample size= 219
b) Required minimum sample size= 271
Step-by-step explanation:
As per given , we have
Margin of error : E= 5% =0.05
Critical z-value for 90% confidence interval : 
a) Prior estimate of true proportion: p=28%=0.28
Formula to find the sample size :-
Required minimum sample size= 219
b) If no estimate of true proportion is given , then we assume p= 0.5
Formula to find the sample size :-
Required minimum sample size= 271
Answer: 9x19=171

Jon has 9times as many mm as lala has 19 more then jon.
Here, we need to set up a proportion.
4.5 miles in 15 minutes.
In 75 minutes, how much miles can he ride?
4.5/15 = x/75
Cross multiply
4.5 * 75 = 337.5
15*x = 15x
15x = 337.5
15x/15 = 337.5/15
x= 22.5
Final answer:- Tommy can ride 22.5 miles in 75 minutes.
