Solution

a) strongest correlation is between Exercise and esteem.

Correlation coefficient(r)=0.843

The r value is close to 1 therefore it is strong correlation.

Weakest correlation is between stress and IQ.

Correlation coefficient (r)=0.225

As r value is away from 1 it is considered as weakest correlation.

b)8 out of 10 total number of unique correlation coefficient are significantly different from 0 using alpha of 0.05.

c) correlation coefficient (r) between esteem and stress is -0.747

The correlation coefficient has negative sign.therefore we can say that esteem and stress are negatively correlated with each other.as correlation is close to -1 we can say that there is strong correlation between stress and esteem.we can interpret that as stress increases,esteem decreases.
