"people who often attend cultural activities, such as movies, sports events and concerts, are more likely than their less cultured cousins to survive the next eight to nine years, even when education and income are taken into account, according to a survey by the university of umea in sweden" (american health, april 1997, p. 20).

(a) can this claim be tested by conducting a randomized experiment? explain.
(b) on the basis of the study that was conducted, can we conclude that attending cultural events causes people to be likely to live longer? explain.
(c) the article continued, "no one’s sure how mel gibson and mozart health, but the activities may enhance immunity or coping skills." comment on the validity of this statement.
(d) the article notes that education and income were taken into account. give two examples of other factors about the people surveyed that you think should also have been taken into account.

Step-by-step explanation:

Given that a claim was made as

"People who often attend cultural activities, such as movies, sports events and concerts, are more likely than their less cultured cousins to survive the next eight to nine years, even when education and income are taken into account, according to a survey by the University of Umea in Sweden" (American Health, April 1997, p. 20).

a) Yes, this can be tested by conducting a randomized experiment.  Selecing two groups of persons i who attend and other who do not attend and compare their life

This can be done from the data source already existing about persons who died recently under homogeneous conditions of environemnt

b) Yes, we can conclude provided random sample are taken and homogeneous conditions were followed

c) Yes, 100% true, though cannot say precisely how these helps as there is no scientific measurement, but it is a fact it improves health.

d) Other factors, are family history, bad habits, disease already present in the persons, etc.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
