In a diabetes study we compared fathers' blood sugar levels and their sons' blood sugar levels. We took a sample of 200 fathers and for each father we measured his blood sugar level and his son's blood sugar level. We obtain correlation coefficient R =.84. That means

A. Diabetes is genetically inherited

B. the lower the father's blood sugar level the lower the son's blood sugar level

C. father's blood sugar level is not significantly different from his son's blood sugar level

D. if a father has a low blood sugar level then his son will have a low blood sugar level

C. father's blood sugar level is not significantly different from his son's blood sugar level.

Step-by-step explanation:

The study consists on comparing the blood sugar levels of sons and the blood sugar levels of their parents. A high correlation indicates that both sugar levels are not significantly different to each other. Then, the right answer is option C.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
