Question
A fundraiser is offering a small gift to people making a donation.  The donor can choose one of four gifts: a mug, a t-shirt, a plush toy, or a water bottle.  The fundraiser would like to know if any of the gifts were more or less popular or were they equal in preference.  The data for n = 40 donors are below:
Assuming all choices would be equally likely to be chosen, what would be the expected frequency (fe) for all groups? O 40 O 25 O 10 O 13.2 QUESTION 4 Calculate chi-square (x) O 12 O 3 O 6.4 O 40 QUESTION 5 What is the statistical decision that should be made from these data? O fail to reject the null, there is not a significant preference for one or more gifts O fail to reject the null, there is a significant preference for one or more gifts O reject the null, there is not a significant preference for one or more gifts O reject the null, there is a significant preference for one or more gifts
