Proved
Step-by-step explanation:
Given that the sample mean and sample standard deviation for the grade point averages of a random sample of 100 college freshmen at a certain university are 2.5 and 0.2 respectively.
Sample size n =100
Std error = s/sqrt 100 = 0.02
For 99% level critical value is 2.575
Margin of error = 2.575*std error
= 0.0515
Confidence interval 99%
= 2.5±0.0515
=(2.4485, 2.5515)
Hence proved
Answer:
x²-8x+16
Step-by-step explanation:
Take g(x) and plug that equation in for x in f(x)
f(g(x))= (x-4)²
=(x-4)(x-4)
FOIL
=x²-8x+16
