Question 13 (1 point) One of the most difficult things to do in statistics is to determine the correct hypothesis test to do for a given scenario. Determine the most appropriate hypothesis test to use for the following scenario: * ********* ******* A B2B Marketing Insider blog of October 7, 2010 examined five currently-used sales closing techniques. Sales scenarios are presented to a sample of 230 purchasing executives. Each subject received one of the five closing techniques or a scenario in which no sales close was achieved. After reading the sales scenario, each executive was asked to rate his/her level of trust in the salesperson on a 7-point scale. The following table reports the six treatments employed in the study and the number of subjects receiving each treatment: Treatments: Sales Closing Sample Size Technique No Close 35 Financial close 35 Time Line close 30 Sympathy close 40 The Visual close 35 Thermometer close 55 (Source: Based on Hawes, J.M. "Do Closing Techniques Diminish Prospect Trust?" from Industrial Marketing Management, September 1996, Volume 25(5)) Is the salesperson's level of trust influenced by the choice of closing method? Test at 5% significance level. The most appropriate hypothesis test to use for this scenario is: O A) t - test for independent means O B) t - test for single population mean C) one-way ANOVA O D) two-population proportion z-test O E) x2 test for goodness of fit
