The correlation coefficient for poor health and not exercising in a group of people is 0.67. analyze the following statement: poor health is caused by not exercising. is this a reasonable conclusion? yes; everyone who doesn't exercise is by definition unhealthy yes; the correlation coefficient is above 0.5, so that implies causation no; the data doesn't suggest a causation, and many people are healthy who don't exercise no; poor health and not exercising are completely unrelated

Base on the statement ‘Poor health is caused by not exercising’, there is a greater chance of having poor health without exercising. It is also said that the correlation between poor health and not exercising a group people is 67%.  

Step-by-step explanation:

Answer with explanation:

⇒Correlation coefficient for poor health and not exercising in a group of people = 0.67(r)

⇒ -1 ≤ r ( Correlation coefficient) ≤ 1

⇒If the value of , r < 0.8 or r > -0.8 , are not considered Significant.

⇒So, there is not strong correlation between people who do not exercise and their health.

The Statement we have to analyze is:→

                           Poor health is caused by not exercising.

Option A: Yes; everyone who doesn't exercise is by definition unhealthy.

⇒Keep in mind:→ Simple Walk is also a Exercise.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

what are ur choices?
