(20 pоints) Cоlоr аnd Creаtivity Reseаrchers from the University of British Columbia conducted trials to investigate the effects of color on creativity. Subjects with a red background were asked to think of creative uses for a brick; other subjects with a blue background were given the same task. Responses were scored by a panel of judges and results from scores of creativity are given below. Higher scores correspond to more creativity. The researchers make the claim that “blue enhances performance on a creative task.” Use a 0.01 significance level to test the claim that blue enhances performance on a creative task.

Belоw is а little mоre infоrmаtion аbout the two campaigns Zappos is considering for the new season. Both campaigns are similar in terms of their overall look and feel, but the content within the two campaigns is different. The ads in campaign 1 (Product-Focus) feature more detail about the new seasonal colors and styles. The ads in campaign 2 (Brand-Focus) feature more information about why to shop at Zappos and highlight Zappos’s brand promise. The Zappos team uses secondary research to glean insights into the consumer mindset and motivations. The secondary research indicates that generally, target audiences could have one of three potential motivations for why they would purchase their shoes online: convenience, cost, or better variety. The secondary research also shows that typically in this industry, the probabilities (or chances) that the consumer purchase is due to one of these three motivations are 0.5, 0.2, and 0.3, respectively. Additionally, the Zappos team uses the secondary research along with their expertise and industry knowledge to determine the payoffs associated with each decision option and associated consumer motivation. Below is the expected payoff table, in terms of number of click-throughs to the website for the online ads, for the different online ad campaigns.
