Multiple Choice

Inc. Technology reported the results of consumer survey in which 300 Internet users indicated their level of agreement with the following statement: ʺThe government needs to be able to scan
Internet messages and user communications to prevent fraud and other crimes.ʺ The possible
Responses were ʺagree stronglyʺ, ʺagree somewhatʺ, ʺdisagree somewhatʺ, and ʺdisagree stronglyʺ.
The number of Internet users in each category is summarized in the table. $\begin{array}{l|l}\text { RESPONSE } & \text { NUMBER } \\\hline \text { Agree Strongly } & 60 \\\text { Agree Somewhat } & 110 \\\text { Disagree Somewhat } & 80 \\\text { Disagree Strongly } & 50\end{array}$

Specify the null hypothesis for testing whether the true proportions of Internet users in each response category are equal.

A) $\mathrm { H } _ { 0 } : \mathrm { p } _ { 1 } = \mathrm { p } _ { 2 } = \mathrm { p } _ { 3 } = \mathrm { p } _ { 4 } = 0.25$ , where $\mathrm { p } _ { 1 }$ represents the proportion of Internet users in one of the four response categories
B) $\mathrm { H } _ { 0 }$ : Internet users and Government scanning are independent
C) $\mathrm { H } _ { 0 } : \mathrm { p } 1 = 60 , \mathrm { P } _ { 2 } = 110 , \mathrm { P } 3 = 80 , \mathrm { p } 4 = 50$ , where $\mathrm { p } _ { \mathrm { i } }$ represents the proportion of Internet users in one of the four response categories
D) $\mathrm { H } _ { 0 } : \mu _ { 1 } = \mu _ { 2 } = \mu _ { 3 } = \mu _ { 4 }$ , where $\mu _ { \mathrm { i } }$ represents the average number of Internet users in one of the found response categories
