Answer:
Option (a) is correct.
The value of given function at x = 3 is -28
Step-by-step explanation:
Given : Function
We have to find the value of given function at x = 3
Consider the given function
Since, we have tof ind the value of function at x = 3
Put x = 3 in given function f(x)
Simplify, we have,
Thus, the value of given function at x = 3 is -28

Step-by-step explanation:
(a)
H0: Consultant with more experience has the higher population mean service rating.
H1: Consultant with more experience doesn't have the higher population mean service rating.
(b)
t = 1.9923 (see the attached image)
(c)
The degrees of freedom for the test statistic,
df = 16
The P-value of the one tailed t- test with 16 degrees of freedom is,
P−value = tdist(X,df,tails)
P-value = tdist(1.9923,16,1)
P-value = 0.032
(d)
Since, P-value 0.032 is less than the significance level 0.05, there is an enough evidence to reject the null hypothesis.
Hence, there is a sufficient evidence to conclude that Consultant with more experience doesn't have the higher population mean service rating.
Hope this helps!
