Answer 1

Hint: Here, we will observe the given eighteen observations, first of find the number fifty $ (50) $ and count the number of required observations and find the total number of repeated required observations.

Complete step-by-step answer:
In statistics, data are very important. Organization of data is most important and these concepts of observation and interpretation is very important. Statistics can be defined as the science which deals with the techniques or the methods for collecting, classifying, interpreting and the presentation of the data and it generally refers to the statistical methods.
Here, first of all, students scored $ 50 $ marks from all the given scores in the quiz competition from the given table.
We can observe that marks $ 50 $ are repeated four times and therefore, four students have secured $ 50 $ marks in the quiz competition.
Hence from the given multiple choices, the option A is the correct answer.
So, the correct answer is “Option A”.
