In 1998, scientists observed 210 deer killed by hunters in Montana, and found that 46 of them carried ticks that had Lyme's disease. In 1999, scientists sampled 187 deer from Montana and found that 36 carried ticks with Lyme's disease. Does these data support the claim that there has been a decrease in the proportion of deer carrying ticks with Lyme's disease? Use a 1% level of significance to test this claim.

What is the null and alternative hypothesis?
