(a) Calculate the YTM for each set of condition and fill up the blank cells in the following table (5 points)

Face value	PMT	n	Price	YTM
1000	80	12	1200
1000	80	12	1100
1000	80	12	1000
1000	80	12	900
1000	80	12	800
1000	80	12	700
1000	80	12	600
1000	80	12	500
1000	80	12	400

2. (b) Based on above table, draw a graph with horizontal axis showing the price and vertical axis showing YTM. Show the graph below and explain intuitively what relation between price and YTM you observe and why. (5 points)
