A Random Group of Desktop Computer Sales Was Selected from an Electronic

question 61

Multiple Choice

A random group of desktop computer sales was selected from an electronic discount chain to analyze the size of monitor purchased with the computer. Is there evidence to reject the hypothesis that the number of monitors is equally distributed between the five types, at $\alpha = 0.05$ ?
$\begin{array} { c c c c c c } \text { Monitor type } & 15 ^ { \prime \prime } \text { CRT } & 15 ^ { \prime \prime } \text { flat panel } & 17 ^ { \prime \prime } \text { CRT } & 17 ^ { \prime \prime } \text { flat panel } & 19 ^ { \prime \prime } \mathrm { Cl } \\ \text { Number of sales } & 13 & 23 & 13 & 10 \end{array}$

• A) There is evidence to reject the claim that the monitors are equally distributed between the five classes because the test value 9.940 > 11.070
• B) There is not evidence to reject the claim that the monitors are equally distributed between the five classes because the test value 11.070 < 9.940
• C) There is not evidence to reject the claim that the monitors are equally distributed between the five classes because the test value 9.488 < 9.940
• D) There is evidence to reject the claim that the monitors are equally distributed between the five classes because the test value 9.940 > 9.488
