What is the difference between Ho and Ha hypothesis?
I am doing an experiment on plant growth but I don't understand the difference between Ho and Ha hypothesis. PLEASE HELP!!! Can I get an example, please?!

Ho is the null hypothesis. It says that there is no significant difference between the two groups being compared or among the more than two groups. You always start with that. If you do find a significant difference, you have disproven Ho and, by implication, supported Ha, the alternate hypothesis.
There can be variations. Ho could be that you have a fair coin. If you flip it 100 times and it comes up tails 90 times, that suggests Ha, that the coin is weighted on one side.
