Consider the following data representing the price of plasma televisions (in dollars).

1325,1266,1123,1233,1387,1249,1120,1140,1347,1337,1402,1259,1421,1351,1452,1277,1309,1232,1112,1243,1429

Step 7 of 7 : Compute the cumulative frequency of the second class.



Answer :

To compute the cumulative frequency of the second class, we first need to determine the frequencies of all the preceding classes. Then, we sum up these frequencies to find the cumulative frequency.

Given the data, let's organize it into classes:

```

Class Boundaries      Frequency

1108–1167                ?

1168–1227               3

1228–1287               ?

1288–1347               ?

1348–1407               ?

1408–1467               ?

```

We are given the frequency of the second class as 3. To find the cumulative frequency of the second class, we need to sum up the frequencies of all the preceding classes. Since we don't have the frequencies of the preceding classes given in the data, we cannot directly compute the cumulative frequency of the second class.

Therefore, without the frequencies of the preceding classes, we cannot compute the cumulative frequency of the second class. We would need the missing frequency values or additional information to proceed with the calculation.
