The cell labeled a is a .

What is a frequency table?

The frequency of an occurrence or a value is the number of times it happens. A frequency table is a list of objects with the frequency of each item shown in the table.

The data is mentioned in the table given below:

We need to find the value of a and b.

Here, Cell Phone+No Cell Phone=Total

To find a:

Add the no lap entries, that is 159+a=207

⇒a=48

To find b:

Add the lap entries, that is 82+11=b.

⇒b=93.

Therefore, the cell labelled a is a joint frequency of 48 and the cell labelled b is a marginal frequency of 93.
