Dr. Moynihan conducts a study examining the relationship between the number of panic attacks a person experienced in the past month, the number of nightmares experienced in the past month, and people's levels of neuroticism (a personality trait characterized by instability, anxiety, and worry). She collects a convenience sample of 50 community college students (25 males, 25 females). Below are her findings.

Anumber of panic attacks in the past month and neuroticism: r = -.03, not sig.

Bnumber of panic attacks in the past month and nightmares in the past month: r = -.14 (p = .05)

Cnumber of nightmares in the past month and neuroticism: r = .48 (p = .003)

Dr. Moynihan has decided to examine one of her relationships with a scatterplot to double-check for a curvilinear relationship. Which relationship will be most important for her to examine?

A) Number of panic attacks in the past month and neuroticism

B) Number of panic attacks in the past month and number of nightmares in the past month

C)
