[Data Set TEXT] 13.40 Mobile device typing strategies. Refer to the Applied Ergonomics (Mar.
2012) study of mobile device typing strategies, Exercise 13.14. Recall that typing style of mobile
device users was categorized as (1) device held with both hands/both thumbs typing, (2) device
held with right hand/right thumb typing, (3) device held with left hand/left thumb typing, (4)
device held with both hands/right thumb typing, (5) device held with left hand/right index finger
typing, or (6) other. The researchers' main objective was to determine if there are gender
differences in typing strategies. Typing strategy and gender were observed for each in a sample
of 859 college students observed typing on their mobile devices. The data are summarized in the
accompanying table. Is this sufficient evidence to conclude that the proportions of mobile device
users in the six texting style categories depend on whether a male or a female is texting? Use =
.10 to answer the question.
