1. What is the solution to this system of equations?

The relationship between two variables partialling out the effect that a third variable has on one of those variables can be exp

TiliK225 [7]

Answer: partial correlation.

Explanation:

partial correlation measures the degree of association between two random variables, with the effect of a set of controlling random variables removed. If we are interested in finding to what extent there is a numerical relationship between two variables of interest, using their correlation coefficient will give misleading results if there is another, confounding, variable that is numerically related to both variables of interest. This misleading information can be avoided by controlling for the confounding variable, which is done by computing the partial correlation coefficient.

Order from greatest to least. 0.386,0.3,0.683,0.836

lisabon 2012 [21]

Answer:

Greatest to least is 0.836 , 0.683, 0.386 , 0.3.

Step-by-step explanation:

Given : 0.386; 0.3; 0.683; 0.836.

To find : which Is greatest to least.

Solution :" We have given 0.386; 0.3; 0.683; 0.836.

In 0.386

Tenth place is 3 and hundredth place is 8

In 0.3

Tenth place is 3 and hundredth place 0

In 0.683

Tenth place is 6 and hundredth place 8

In 0.836.

Tenth place is 8 and hundredth place 3.

So, Greatest number is 0.836 ,

Least number is 0.3.

Therefore, Greatest to least is 0.836 , 0.683, 0.386 , 0.3.

Dill and Bromberg, Problem 1.23. The San Francisco football team plays better in fair weather. They have a 70% chance of winning

shtirl [24]

Answer:

a) 40% probability that San Francisco will win.

b) 80% probability that the weather was bad

Step-by-step explanation:

We have these following probabilities:

60% chance of snow(bad weather).

If there is bad weather, 20% probability of SF winning.

100-60 = 40% chance of good weather.

If there is good weather, 70% probability of SF winning.

(a) If they play in the Super Bowl in Wisconsin and the weatherman predicts a 60% chance of snow that day, what is the probability that San Francisco will win.

20% of 60%, plus 70% of 40%. So

0.2*0.6 + 0.7*0.4 = 0.4

40% probability that San Francisco will win.

(b) Given that San Francisco lost, what is the probability that the weather was bad?

We use the conditional probability formula to solve this question.

Conditional probability:

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: SF losing

Event B: Bad weather

P(A)

From a), 40% probability that SF wins. So 100-40 = 60% = 0.6 probability that SF losses.

So $P(A) = 0.6$

P(A and B)

60% chance of snow. If it snows, 80% probability of SF losing. So

$P(A \cap B) = 0.6*0.8 = 0.48$

$P(B|A) = \frac{0.48}{0.60} = 0.8$

80% probability that the weather was bad
