1. Find the class midpoints of the first three classes (20-29,30-39, and 40-49) 2. Is the data displayed in the frequency table approximately normal? Explain your reasoning

p2.q2) Can anyone help me with that question? It is easy but i am confused. Thank you

Use the Histogram tool to develop a frequency distribution and histogram for the number of months as a customer of the bank in the data below. Compute the relative and cumulative relative frequencies and use a line chart to construct an ogive.   Complete the frequency distribution for the months as a​ customer, and compute the relative and cumulative relative frequencies. ​(Type integers or decimals rounded to three decimal places as​ needed.)
