Expert Solution

Step 1

Note:

Hi there! Thank you for posting the question. As there are multiple sub parts, according to our policy we have solved the first three sub parts. If you need help with other sub parts, please re post separately.

Step 2

The frequency of a class or observation is the number of values corresponding to it.

The cumulative frequency of that class or observation is the sum of the frequencies up to that particular observation, including that of the observation, in an ordered (increasing or decreasing) arrangement of the data.

The relative frequency of a certain class or observation in a data set is obtained by dividing the class or observation frequency by total frequency.

The sum of relative frequencies is equal to 1.
