I surveyed 48 randomly selected residents of the apartment complex where I live to determine their voting habits. I can only use this information to generalize to all the residents if :
a. there is evidence of a normal population distribution
b. the 48 residents all have the same voting habits.
c. the 48 residents are equally divided in their voting habits.
d the sample distribution is not normal in shape.
By the theorems presented in the text, we know that the mean of a sampling distribution of sample means will be
A. the same as the population mean
B. close to the value of the sample mean
C. between the population and sample means in value.
D. representative of the entire population.
