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

CONDITIONAL PROBABILITY URGENT?

a_sh-v [17]

Let the event $A=\{ Horse \}, B=\{ Female \}$

The the probability of the events

$P(A \cap B)=\frac{2}{14+26} =\frac{1}{20}$

$P( B)=\frac{26}{14+26} =\frac{13}{20}$

The conditional probability

$P(Horse|Female)=P(A|B)=\frac{P(A \cap B)}{P(B)} =\frac{1/20}{13/20} =\frac{1}{13}$
