Find the upper limit \[50 - 55\]

Hint:
Here, we have to use the concept of lower limit and upper limit of class intervals from statistics. Lower limit of a class is the lowest value of that particular class interval and the upper limit of a class is the highest value of that particular class interval. By this concept we will be able to find out the upper limit of the given class interval.

Complete step by step solution:
Given class interval is \[50 - 55\].
So, by the definitions we know that Lower limit of a class is the lowest value of that particular class interval and the upper limit of a class is the highest value of that particular class interval.

Therefore, the upper limit of the given class interval is 55.

Note:
Statistics is the science of collecting some data in the form of the number and studying it to forecast or predict its future possibility. An array is an arrangement of numbers or symbols in rows and columns. Frequency is defined as the number of times a value or some particular data is repeating itself. Frequency arrays help us a lot for the prediction and probability purpose and it also helps us to analyse the real life data like to predict the sale of some specific product or to analyse the sales of the same type of products in the market. Also Frequency distribution is defined as the distribution of frequency corresponding to some class intervals.
Lower limit of a class is the lowest value of that particular class interval and the upper limit of a class is the highest value of that particular class interval.
Mean is equal to the ratio of sum of the total numbers and total count of the numbers. Mean is also known as the average of the numbers.
Mode is the most common or most repeating numbers in the given data.
Median is the middle value of the given list of numbers or it is the value which is separating the data into two halves i.e. upper half and lower half.
