Answer: The value of test statistic is 2.442.
Step-by-step explanation:
Since we have given that
n = 238
Sample mean = 23.2 minutes
Standard deviation = 20.26 minutes
Hypothesis :

So, the test statistic value would be

Answer:
It is CD
Step-by-step explanation:
because 300+200=500, juts times it by 3 and divide
24q-8=11 (use distributive property)
24q= 11+8
24q = 20
q= 20/24
q= 0.8
Answer:
f-1 (x) = 2x + 2
Step-by-step explanation:
f(x) = x/2 -1
y = x/2 -1
interchanging the position of x and y
x= (y-2)/2
2x =y - 2
y = 2x + 2
f^-1 (x) = 2x + 2
