start low reach a maximum then become low agan and are sough

start low, reach a maximum, then become low agan, and are soughly symmetnio about the maximum frequancy MacBook

Solution

comparing the table we see that frequencies are 5 for 3 classes and 4 for other two classes.

Hence no bell shape distribution.

Also there are 3 modes unlike in a normal distribution with unimode.

No symmetry is found around mean = 4.6

Hence option E is right answer.
