Researchers studying pleasant touch sensations measured the firing frequency (impulses per second) of nerves that were stimulated by light busing stroke on the form and also recorded the subject's numerical rating of how pleasant the sensation was. The accompanying data was read from a graph in a poper Firing Frequency Pleasantness Rating 23 0.3 24 1.0 22 1.2 25 1.2 28 10 29 2.0 23 32 2.2 37 2.5 34 (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 (Use technology or the Distribution Calculators page in SALT to find the critical value. Round your answers to three decimal places) Interpret the resulting interval

33 22 34 2.2 (a) Estimate the mean change in plenantes rating associated with an increase of 1 impulse per second in firing frequency using an interval technology or the Distribution Calculators page in SALT to find the critical value Round your answers to three decimal aces) Interpret the resulting interval We are 95% confident that the mean change in firing frequency associated with an increase of 1 in pleasantes rating is in this interval We are 95% confident that the mean change in pleasantness rating associated with an increase of timpulse per second Infering frequency is the We are 95% confident that the mean change in pleasantness rating associated with an increase of 1 impulse per second in firing frequency is outside this vera We are 95% confident that the mean change in tiring frequency associated with an increase of 1 in pleasantruss rating is outside this interval (b) Carry out a hypothesis test using a -0.05 to decide if there is convincing evidence of a useful linear relationship between firing frequency and pleasantness twing Calculate the test statistic (Round your answer to two decimal places.) Use technology to find the p-value for this test. (Round your answer to four decimal places) P-value What can you conclude? Fall to reject Hy. We have convincing evidence of a useful inear relatkunstip between firing frequency and pleasantness rating a Fail to reject H. We do not have convincing evidence of a useful linear relationship between firing frequency and pleasantes rating Reject HoWe do not have convincing evidence of a useful linear relationship between fring frequency and pleasantress rating, Reject Hy we have convincing evidence of a useful linear relationship between firing frequency and pleasantness rating
