The average age of online consumers a few years ago was 24.1 years. As older individuals gain confidence with the Internet, it is believed that the average age has increased. We would like to test this belief. Answer parts a) through e) below. a) Write the appropriate hypotheses. Choose the correct answer below. A. Upper H 0 : mugreater than24.1 years Upper H Subscript Upper A Baseline : muequals24.1 years B. Upper H 0 : muless than24.1 years Upper H Subscript Upper A Baseline : muequals24.1 years C. Upper H 0 : muequals24.1 years Upper H Subscript Upper A Baseline : mugreater than24.1 years D. Upper H 0 : muequals24.1 years Upper H Subscript Upper A Baseline : muless than24.1 years

The correct option is (C).

Step-by-step explanation:

A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.  

It is a hypothesis of no difference.

It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.

Whereas the alternative hypothesis is a contradicting statement tot he null hypothesis. It is denoted by Hₐ.

In this case we need to test whether the average age of online consumers has increased or not.

From previous data we know that the average age of online consumers a few years ago was 24.1 years.

A one-sample mean test can be used to determine whether the mean age has increased or not.

The hypothesis for the test can be defined as follows:

H₀: The average age of online consumers is 24.1 years, i.e. μ = 24.1.

Hₐ: The average age of online consumers is more than 24.1 years, i.e. μ > 24.1.

Thus, the correct option is (C).

the answer is c.

step-by-step explanation:

the answer is 8/21
