Choose all that apply.a ) Certain analytics algorithms can tolerate (i.e., work with) data with missing valuesb) Missing values must be imputed using best guesses.c) Records with missing values must be dropped.d) The pattern of missing values needs to be analyzed to determine how to handle missing values2) In the U.S., college applicants usually take SAT (a standardized test) and submit their test scores as part of their applications. Some schoolsmade SAT score optional, however, students with good sores still choose to submit their scores. As a result, there are missing values for SAT score in the application dataset.
