The value of F(3) = 27.
Step-by-step explanation:
Step 1:
F(x) is dependent on the value of x.
So x is independent while F(x) is dependent on x i.e. the value of F(x) depends on the value of x.
Step 2:
F(x) = , if we have the x's value we can calculate the F(x)'s value.
Here the value of x is given as 3 so F(x) when x equals 3 can be calculated.
So F(3) = 27.
Answer:
See the explanation
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!
