Indicate whether the following statements are true, false, or uncertain, and provide a short (no morethan three sentences) justification of your response.1.Consider a setting where two researchers are trying to estimate the relation betweena specific variable of interest x and an outcome variable y. While the first researcher (we shallcall her A) has been very careful in the measurement of y, the second one (researcher B) hashad problems with data entry, which resulted in the outcome being observed with a substantialamount of measurement error. As long as the measurement error is independent of x, weexpect the range of estimates the two researchers will get to be the same.

Summary of Statements: When y has a measurement error that is independent of x, the range of…
