Answer:
(b) 6.25%
Step-by-step explanation:
Margin of error is the chances of percentage deviation that may differ from original population data. The margin of error for 95% confidence interval can be 6.25%. To find this we divide population standard deviation with square root of sample size. The margin of error is the estimate of the deviation from actual and real value of population.
H (4.84) will be the correct answer
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.
