Chapter 13.2, Problem 23E
Researchers studying pleasant touch sensations measured the firing frequency (impulses per second) of nerves that were stimulated by a light brushing stroke on the forearm and also recorded the subject’s numerical rating of how pleasant the sensation was. The accompanying data was read from a graph in the paper “Coding of Pleasant Touch by Unmyelinated Afferents in Humans” (Nature Neuroscience, April 12, 2009).
- a. Estimate the
mean change in pleasantness rating associated with an increase of 1 impulse per second in firing frequency using a 95% confidence interval. Interpret the resulting interval. - b. Carry out a hypothesis test to decide if there is convincing evidence of a useful linear relationship between firing frequency and pleasantness rating.
