The table shows the number of calories in four meals and the cost of each meal.

Aleksandr-060686 [28]

Answer:

A weak negative correlation

Step-by-step explanation:

$correlation, r = \frac{∑(y-\alpha)(x-\beta }{\sqrt{∑(y-\alpha)^2∑(x-\beta )^2 } }$

where,

$\alpha = \frac{∑y}{n} \\\beta =\frac{∑x}{n} \\∑ = summation$

$\alpha = \frac{3230}{4} = 807.5\\\\\\\beta =\frac{46}{4} = 11.5$

$therefore,\\\\r= -0.12924$

This represents a weak negative correlation
