John was feeling depressed and anxious. His therapist gave him a depression test (M = 10, s = 3), higher scores mean more depression) and an anxiety inventory (M = 80, s = 25, higher scores mean more anxiety). His score was a 15 on the depression test and a 110 on the anxiety inventory. Is John more depressed than anxious, or more anxious than depressed?

Taylor Swift is interested in learning what proportion of her fans want her to re-record her masters, so she takes a simple random sample of 500 fans and asks them.  Of the 500 fans, 487 of them (97.4%) respond that they want her to re-record all of her masters.  What is the parameter and what is its value?   a. The parameter is the average number of all Taylor Swift fans who want her to re-record her masters, which is unknown.   b. The parameter is the proportion of the sampled Taylor Swift fans who want her to re-record her masters, which is unknown.   c. The parameter is the group of the sampled Taylor Swift fans who want her to re-record her masters, which is 487.   d. The parameter is the proportion of the sampled Taylor Swift fans who want her to re-record her masters, which is 0.974.   e. The parameter is the proportion of all Taylor Swift fans who want her to re-record her masters, which is unknown.   f. The parameter is the proportion of all…
