Answer 1

null hypothesis states no statistical significance where as alternative hypothesis states statistical significance.

null hypothesis represents all other values and which ever hypothesis is accepted is decleared true by the statisfaction.

1. one side alternative hypothesis ;- Because it consider only one part of the tail that is the negative part

2. two sided alternative hypothesis ;- It consider both parts

3. one sided alternative hypothesis ;- It consider only positive part of the tail

one sided alternative hypothesis states value is either greater thanor less than u but not both, where as a two sided alternative hypothesis is simply states the value is not equal to u
