put one point on (-3,5) and another point on (2,3)
Answer: a) 84 and b ) 2084
Step-by-step explanation:
Given : Sample standard deviation : s= $22.82
(Population standard deviation is unknown ) , so we use t-test.
Critical value or the 95% confidence intervals :
Formula to find the sample size :

a) E = 5


i.e. Required sample size : n= 84
b) E = 1


i.e. Required sample size : n= 2084
So here we just are gonna distribute and simplify.
You have ridden 55% of the way.
You have to set up a proportion 44 over 80 is equal to x over 100 (x is what we are trying to find - the percentage you have ridden). Then use cross products and multiply the 44 by 100 to get 4400 and divide that by 80 to get 55. So the answer is 55 so 55%.
55%.
Hope this helps!
