Chapter 11: Q.2.1 (page 703)

In the previous Check Your Understanding (page 698), we presented data on the use of Facebook by two randomly selected groups of Penn State students. Here are the data once again.
Do these data provide convincing evidence of a difference in the distributions of Facebook use among students in the two campus settings?
State appropriate null and alternative hypotheses for a significance test to help answer this question.

Short Answer

Expert verified

The null and alternative hypotheses are:

H_{0} : (\begin{matrix} There is no difference in the distribution of Facebook use between \\ students at Penn state's campus and its commonwealth campuses. \end{matrix})

$H_{a} : (\begin{array}{l} There is a difference in the distribution of Facebook use between \\ students at Penn state's campus and its commonwealth campuses. \end{array})$

Step by step solution

Given Information

The table is,

Explanation

It is required to check whether sufficient evidence exists that indicates that there is a difference in the use of Facebook among students in the two campus settings.

The null and alternative hypotheses are:

$H_{0} : (\begin{array}{l} There is no difference in the distribution of Facebook use between \\ students at Penn state's campus and its commonwealth campuses. \end{array})$

$H_{a} : (\begin{matrix} There is a difference in the distribution of Facebook use between \\ students at Penn state's campus and its commonwealth campuses. \end{matrix})$
