Step-by-step explanation:

it is given that there is one variable with 1000 records

we have to find the records which is expected would be removed

it is given that one variable is missing with 5% that 0.05

we can find missing records by multiplying total number of records and the missing value with one variable

so the expected record removed will be = 0.05*1000=50
