1. The problem asks for the limits and frequencies of specific clusters in a data set. 2. The "limits" of a cluster refer to the range of values it covers, typically the lower and upper boundaries. 3. The "frequency" of a cluster is the number of data points that fall within that cluster. 4. To find the limits of the lowest cluster, identify the smallest range of values in the data set. 5. The frequency of the lowest cluster is the count of data points within that range. 6. Similarly, the frequency of the fifth cluster is the count of data points in the fifth range or group. 7. Since the exact data is not provided, the general approach is: - Determine the class intervals or clusters. - Count the number of data points in each cluster. 8. For example, if clusters are defined as intervals like 0-10, 10-20, etc., the lowest cluster is 0-10. 9. The frequency is the number of data points within those intervals. 10. Without specific data, exact numerical answers cannot be given. Please provide the data or class intervals and frequencies to calculate precise values.
