b. due to nonresponse
c. due to confounding
d. a pattern in a time series that repeats itself at known regular intervals of time
e. the margin of error - Answer>>> d. a pattern in a time series that repeats itself at known
regular intervals of time
Test1-Bias in a sampling is:
a. any error in the sample result, that is, any deviation of the sample result from the truth about
the pop'tn.
b. any systematic error that tends to occur in the same direction every time you use this sampling
method
c. any error due to practical difficulties like contacting the subjects selected
d. the random error due to using chance to select a sample - Answer>>> b. any systematic error
that tends to occur in the same direction every time you use this sampling method
Test1-The drug manufacturer Merck recently stopped testing a promising new drug to treat
