answer is no In a 60day period in Ithaca 12 days were rainy

answer is no

In a 60-day period in Ithaca 12 days were rainy. Is this observation consistent with the belief that the true proportion of rainy days is 1/3?

Solution

No

Rainy days =12

Non rainy days=60-12=48

So proportion of rainy to non rainy=12/48=1/4

which does on agree with believed proportion of 1/3
