Social warmth is a term referring to the feeling of being connected to others. A study published in PLoS One in 2016 looked at a potential relationship between physical warmth (body temperature) and social warmth among a group of 54 volunteers (Inagki et al.). These volunteers had their oral temperature taken by a registered nurse and then assessed themselves using a scale of 1 to 5 on twelve items related to a feeling of social connection for which the average was recorded. Higher average scores indicated higher levels of social warmth. The theory was that the thermoregulatory system, which helps maintain a relatively warm internal body temperature, may also help people assess feelings of social connection. Below is a scatterplot and least-squares regression line of the data.
-Based off of the simulated null distribution in question 51, what is the strength of evidence against the null hypothesis?
A) We have strong evidence against the null hypothesis.
B) We have moderate evidence against the null hypothesis.
C) We have weak evidence against the null hypothesis.
D) We have no evidence against the null hypothesis.

The strength of evidence against the null hypothesis is determined by how extreme the observed data is compared to the simulated null distribution. If the observed data falls in the tail of the distribution, it indicates strong evidence against the null hypothesis.
