a gym surveyed 100 female members. these members were chosen at random from the gym's membership database. participants were asked the question, "do you prefer to use the easy weight-lifting machines or the harder free weights? "

a report of the survey results stated that female members at the gym prefer the weight-lifting machines over the free weights.

select all statements that correctly evaluate the report

answer:

2 and 3

step-by-step explanation:

the sample is not a biased sample as it is 100 random female members of the gym. however, the question is biased as it labels the weight lifting machines as easier than the free weights, calling the latter more difficult.

answer should have two statements:

1) the question is biased towards a response of preferring to use weight-lifting machines.

2) the sample is not biased.

the answer is d

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
