b. Interpret your interval in context. C. Does your interval contain the value of zero, and what information does this provide about the true mean difference? 7. In the paper "The Relation of Sex and Sense of Direction to Spatial Orientation in an Unfamiliar Environment" (Journal of Environmental Psychology, Vol. 20, pp. 17-28), J. Sholl et al. published the results of examining the sense of direction of male and female students. After being taken to an unfamiliar wooded park, the students were given some spatial orientation tests, including pointing to south, which tested their absolute frame of reference. The statistics below are for the absolute pointing errors, in degrees, of participants in a replication of the original study. Male x = 43.8 Female x = 50.2 s = 19.5 n = 28 s = 23.1 n = 25 a. Construct a 90% confidence interval for the true mean difference in the absolute pointing error between male and female participants. Include the form your interval takes, the setup with the value for either za 2 or ta½2, the order of your subtraction, and the resulting lower and upper bounds of the interval.
