Answer:
The answer to this question is D: None of the above
Step-by-step explanation:
From the example given in the question, this is a bad way of data sampling. The example in the question is a typical Voluntary response sample. In this type of sampling, the researcher creates a request as the case may be in the example through television, and ask for members of a population to join. Thus people then choose to be part of the sample or not. In this type of sampling, the respondents tend to have alike opinion in contrast to the rest of the population. This therefore makes voluntary response sample kind of bias.
Answer: The weight of the iceberg at the end of the day will be 449,100 lbs.
Step-by-step explanation: The question is solved by first calculating what the loss of weight is during the day. The question indicates that it will lose .2%. In order to calculate the loss you need to multiply 450,000 x .002, which equals 900. Next, we subtract the weight loss from the original weight to determine the end of day weight. 450,000 - 900 = 449,100 lbs.

Answer:
1/8 of the number of students
Step-by-step explanation:
1/4 + 1/3 + 1/8 + 1/6 =
= 6/24 + 8/24 + 3/24 + 4/24
= 21/24
= 7/8
7/8 of the class chose drinks.
1 - 7/8 = 8/8 - 7/8 = 1/8
That means that 1/8 did not have a drink.
Since we don't know the number of students in her class, we cannot tell the number of students who did not have a drink, but we do know it is 1/8 of the number of students.
