Which of the following is FALSE? a. Nonsampling errors contribute more than sampling errors to total error in most surveys. b. Nonsampling errors are not as manageable as sampling errors. c. Reduction of nonsampling error depends on improving method

Non Sampling errors are not as manageable as sampling errors.

Step-by-step explanation:

Sampling Error is the error due to using sample method rather than analysing entire population. Ex : Difference between population mean & sample mean. This error can be easily reduced by increasing the sample size, & making sample a better representative of population.

Non Sampling Errors are the errors due to improper handling of data. It includes errors like wrong data figures entered, wrong analysis of data etc. It is very complex to be handled than sampling error, variant solutions to dynamic & diverse non sampling errors.

b

step-by-step explanation:

multiply terms on numerator/ denominator by (x - 1)

= ← distribute numerator/ denominator

= ← simplify

=

= → b
