Twenty-nine college students, identified as having a positive attitude about Mitt Romney as compared to Barack Obama in the 2012 presidential election, were asked to rate how trustworthy the face of Mitt Romney appeared, as represented in their mental image of Mitt Romney’s face. Ratings were on a scale of 0 to 7, with 0 being “not at all trustworthy” and 7 being “extremely trustworthy.” Here are the 29 ratings: 2.6 3.2 3.7 3.3 3.4 3.6 3.7 3.8 3.9 4.1 4.2 4.9 5.7 4.2 3.9 3.2 4.5 5.0 5.0 4.6 4.6 3.9 3.9 5.3 2.8 2.6 3.0 3.3 3.7 a 95% confidence interval for the mean rating. Is there significant evidence at the 5% level that the mean rating is greater than 3.5 (a neutral rating)?
State H0 and what is H1 for all of them a, b and c a) The marketing researcher would like to find out whether consumers from different regions evaluate brand A differently when they see the brand name b) The marketing researcher would like to find out whether consumers from the south region and the north region evaluate brand B differently when they see the brand name c. The data file contains four taste evaluations. The taste evaluations were measured on a scale from 1 to 10 (with 10 the highest evaluation). Brand equity of one brand for one respondent is the difference of branded score and unbranded score of that brand evaluated by the respondent. The marketing researcher would like to find out whether brands A and B have brand equity, in other words, whether the evaluation of brand A (B) is different when consumers can see the brand name vs. when they cannot see the brand name.
