Answer:
The value of the test statistic is
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, is the null hypothesis value,
is the standard deviation and n is the size of the sample.
In this problem:
So
The value of the test statistic is
The inverse of the function x^7 is x^-7 and it is also a function.
An inverse function or an anti function is defined as a function, which can reverse into another function.
A standard method to find inverse of a function is to set y=f(x)
let y= f(x)=x^7
thus
=x
thus (y)=
thus
(To verify this if a function is inverse or not we are required to check for the identity)
f((x))=
(f(x))=x
Therefore, The inverse of the function x^7 is x^-7 and it is also a function.
