Answer:
Non-response bias
Step-by-step explanation:
Selection bias in a survey occurs when individuals are selected in a disproportionate way such that the samples obtained do not represent the true population to be studied or interviewed. An example of a selection bias that can occur from Random-digit dialing is the non-response bias.
Participants who are to be selected for surveys must be eligible or suitable for the purpose of the experiment. If the survey is trying to measure the effect of stress on parents, there is a possibility that through random-digit dialing, homes might be called at times when parents are on a work trip. This inability to get the response of eligible subjects for the survey is a form of selection bias.
Answer:
Mode:7
Median:2
Mean:5.2
Range:7
Step-by-step explanation:
see the picture attached
A° = 38, b°= 90, c° = 38
the square on the angle opposite to b shows that it is a right angle which means it’s 90°
For number 12 the answer is 15.36
In some cases, there are better solutions than factoring. Consider, for example the quadratic equation x^2+x+1, which is much easier to solve using the quadratic formula than by factoring.
