Step-by-step explanation:
Given : The quality control manager of a soda manufacturing company wishes to use a significant level of 0.05 to test whether the variabilities in the amount of soda in the company's 16 OZ bottles is more than the variabilities in the company's 12 OZ bottles.
Let
represents the variance for 16 OZ bottles and
represents the variance for 12 OZ bottles.
The Null and Alternative Hypothesis will be :-

, since alternative hypothesis is left-tailed , then the test is left-tailed test.
By using the standard normal distribution table for z, the critical value for this hypothesis:-

Answer:
discount=MP-SP
=Rs420-Rs405
=Rs15

Answer:

Step-by-step explanation:
We are given the function:

Let's find the inverse of g.
Call y=g(x):

We need to solve for x. Multiply both sides by x-2 to eliminate denominators:

Operate:

Collect the x's to the left side and the rest to the right side of the equation:

Factor the left side and operate on the right side:

Solve for x:

Interchange variables:

Call y as the inverse function:
