Explanation / Answer

Here we want to test for number of hospitals LPN has decreases or not so the test is for poisson distribution 's lambda

Where assuming number of hospitals in city is countablly infinite

2) here we want to compare means of two groups. So two samples t-test will be applicable

3) there is test for different groups so here Analysis of Variance will be applicable

4) test for association is many kinds but one most commonly used test is kendall tau a and b
