Answer:

A weak negative correlation

Step-by-step explanation:

[tex]correlation, r = \frac{∑(y-\alpha)(x-\beta }{\sqrt{∑(y-\alpha)^2∑(x-\beta )^2 } }[/tex]

where,

[tex]\alpha = \frac{∑y}{n} \\\beta =\frac{∑x}{n} \\∑ = summation[/tex]

[tex]\alpha = \frac{3230}{4} = 807.5\\\\\\\beta =\frac{46}{4} = 11.5[/tex]

[tex]therefore,\\\\r= -0.12924[/tex]

This represents a weak negative correlation
