Students were asked how many hours during the weekend they studied for a Monday exam. Each row of the table represents one sample from the class. Find the mean of each sample. Mean of samples in row 1: Mean of samples in row 2: Mean of samples in row 3: Mean of samples in row 4:
Mean of samples in row 2:
Mean of samples in row 3:
Mean of samples in row 4:
Which statements are true? Check all that apply.
Looking at the means of the samples, which of these values is least likely to be the mean of the population the samples were taken from?
Looking at this table of sample means, which value is the best estimate of the mean of the population?
The mean of the population is . The mean of the sample is . The difference between the mean of the sample and the mean of the population is .
Will all random samples from a given population have the same mean? Provide an explanation with your answer.
Data from random samples will not always include the same values. Values are chosen randomly and they may or may not be the same. So means will vary among samples.
If Serena selects 4 samples from the table, which row will give her the largest mean? Which row will give her the smallest mean? The actual population mean will be between .
Looking at this table of sample means, which value is the best estimate of the mean of the population?
