Students taking an exam are divided into two groups, P and Q such that each group has the same number of students. The performance of each of the students in a test was evaluated out of 200 marks. It was observed that the mean of group P was 105, while that of group Q was 85. The standard deviation of group P was 25, while that of group Q was 5. Assuming that the marks were distributed on a normal distribution, which of the following statements will have the highest probability of being TRUE?

Option 1 :

The table can be re - drawn as:

Lower limit	Upper limit	Number of students with marks in this range	Cumulative count
0	5	10	10
5	10	20	30
10	15	70	100
15	20	80	180
20	25	55	235
25	30	90	325
30	35	67	392
35	40	53	445
40	45	54	499
45	50	76	575
50	55	24	599
55	60	16	615
60	65	105	720
65	70	80	800

So, the cumulative frequency graph will be as follows:
