Hello

Can I please have help with the following questions:

Q.1 How do you find the median from a frequency table (below suppose to be a table):

score: 15 20 25 30 35 40 45 50

Frequency: 2 3 7 8 8 7 3 2

Q.2How do you find the mean of a Frequency Histogram by using the mid-point of each class interval?

Thank you
