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.

The selling price of an apartment dropped from 250,000 to 225,000. By What percent did the price drop?

ch4aika [34]

Answer:

10%

Step-by-step explanation:

The percentage decrease in price = $\frac{decrease amount}{original amount}$ x 100%

Original amount = 250,000

New amount = 225,000

Decrease in amount = 250,000 - 225,000

= 25,000

So that;

Percentage decrease in price = $\frac{25000}{250000}$ x 100%

= 0.1 x 100%

Percentage decrease in price = 10%

The price of the apartment dropped by 10% of its original price.
