Answer:
Option b.
Step-by-step explanation:
Sample size n = 9
sample mean = 217.222
Standard deviation s = 1.202
alpha a = 0.025
H0 : u = 216
H1 : u > 216 ( claim)
Now run a T test and result is :
Test statistic, t =
t =
=
t = 3.0509
Critical value = t(a,n-1) = t(0.025,9-1)
= 2.306
Since t > critical value, Hence reject H0.
Option b. is the answer. Yes, because computed t is greater than the critical value.
Now, if x = 300 miles, then
y= 1/20*300 + 35
y = 15 + 35
y = 50, therefore it would cost $50.00 to drive the rental car 300 miles.
So multiplying two rationals is the same as multiplying two such as fraction as when you multiplying two rational numbers produces another rational number.
What? I don’t understand lol
Hello!
As an expression this problem is 5-x².
I hope this helps!
