In a course on reasoning and decision-making, you heard about a phenomenon called anchoring and adjustment (Epley \& Gilovich, 2006; Tversky \& Kahneman, 1974). The phenomenon suggests that the way a question is asked can influence the answer people give. Could this phenomenon help increase sales in a grocery store? Specifically, does providing a high anchor to shoppers increase the number of items they buy? You enlist the help of two branches of a neighborhood grocery store chain. The stores are in similar locations with similar demographics and with similar sales figures. One store posts signs advertising a sports drink at the price "10 for $10 " (high anchor). The other store posts signs advertising " 5 for $5 " (low anchor). Both signs also indicate that the price for one bottle is $1. Computerized cash registers recorded the number of bottles purchased by each shopper at each store. The daily sales of sports drinks across a year do form a normal distribution. The number of bottles sold to each shopper at each store are below: Store 1: Low Anchor (5 for $5 ); M1=6.00,SD1=2.39,n1=15 Store 2: High Anchor (10 for $10 ); M2=9.47,S2=3.29,n2=15 Find the two-tailed p-value for the obtained t using the Textbook Calculator. Is the two-tailed p-value evidence against the null hypothesis (i.e., should we reject the null hypothesis or fail to reject the null hypothesis based on the pvalue)? two-tailed p-value = Determine whether we should reject the null hypothesis or fail to reject the null hypothesis?
