6.4n^2 is correct. math papa helps
Answer:
you would need 30
Step-by-step explanation:
18/3=6
6*5=30
We use the formula:
x± s <span>t_<span>(1−c)/2 / </span></span>√n = 5
(1 - c)/2 = (1 - 0.95) / 2 = 0.025
Using the t score calculator at this value, at the 95% confidence internval,
t = 0.5080, So
100 - 19(0.5080) / √n = 5
Solving for n
n = 97
a) 97
b) yes
Answer:
1 more than n squared
