An I/O (Industrial/organizational) Psychologist Tested Consumer Reaction to Two Methods $\alpha$

An I/O (industrial/organizational) psychologist tested consumer reaction to two methods of unit pricing of canned fruit juice. One method provided price per ounce and the other gave price per pound. The consumers filled out a questionnaire in which higher scores represent a more favorable reaction. A different sample of consumers was used for each method. Set $\alpha$ = .05, run a two-tailed test, and determine if the two methods result in different consumer reactions.
$$\begin{array} { c c } \text { Price per Ounce } & \text { Price per Pound } \\\hline 43 & 46 \\70 & 72 \\25 & 38 \\36 & 84 \\34 & 69 \\55 & 73 \\51 & 65 \\80 & 79 \\76 & 47 \\55 & 26 \\40 & 57 \\20 & 61\end{array}$$
