Grab users’ satisfaction. Refer to the research data for users’ satisfaction with the services provided by Grab, Exercise 8.72 (p. 496). Recall that the respondents comprised 60 staff and students at University Sains Malaysia (USM) who were asked to rate their level of satisfaction with the safety of their ride. Out of these, 16 participants chose “Excellent,” 15 chose “Good,” 26 chose “Satisfactory,” 3 chose “Poor,” and none chose “Very Poor.” Suppose that the Grab company expects 20% of the users to choose “Excellent,” 25% to choose “Good,” 20% to choose “Satisfactory,” 25% to choose “Poor,” and 10% to choose “Very poor.” Does the observed distribution of safety satisfaction levels match with the Grab company’s expectations? Test using a = .05.
