A technology manufacturer is a supplier of fiber optic cables. They are interested in expanding their business and offering fiber optic cable installation to internet providers. A recent article in a technology journal states only 45% of internet providers currently offer fiber optic internet in the United States. As the first step in hypothesis testing, the technology manufacturer claims the proportion of internet providers offering fiber optic internet in the United States is different than 45%. What does this claim represent in hypothesis testing?

Alternate hypothesis

Step-by-step explanation:

We are given the following in the question:

Proportion of internet providing fiber optic internet in the United States

p = 11.3% = 0.113

Claim:

It is claimed by the technology manufacturer that this proportion is different from 45%

First, we design the null and the alternate hypothesis  

Alternate hypothesis:

The claim is expressed by the alternate hypothesis that the the percentage of fiber optic internet offered in the United States is different from 45%.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
