For many years "working full-time" was 40 hours per week. A business researcher gathers data on the hours that corporate employees work each week. She wants to determine if corporations now require a longer work week. Group of answer choices Testing a claim about a single population proportion. Testing a claim about a single population mean. Testing a claim about two population proportions. Testing a claim about two population means.

Correct option is: Testing a claim about two population means.

Step-by-step explanation:

In this provided scenario, a researchers wants to determine if corporations require a longer work week for the employees "working full-time".

It is given that for many years "working full-time" was 40 hours per week.

The researchers researcher gathers data on the hours that corporate employees work each week.

It is quite clear that the researcher wants to determine whether the number of hours worked per week must be increased from 40 hours or not.

A test for the difference between two population means would help the researcher to reach the conclusion.

Thus, the correct option is: Testing a claim about two population means.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
