The number of Rainy days in a week Year at a certain place is given below....
Assume that the number of rainy days per month in a given city follows a Poisson distribution with a mean value of 2.4 days. What is the probability that it will rain two or more days next month?
3. Let the amount of rain on rainy days be normally distributed with a mean of 3 cm and standard deviation of 1cm. (a) Find the probability that there is at least 2cm of rain on a randomly chosen rainy day. You can use a normal table to get the probabilities needed or use pnorm() in R. Do get a final answer that is numerical and not just a function of Φ(), the standard normal cdf. (b) Suppose on rainy...

As an instant relief from rainy days or cloudy skies... do Mathematics! Given that: Then if: x + y = 6666 6 + 4 = 210 9 + 2 = 711 8 + 5 = 313 5 + 2 = 37 7 + 6 = 113 9 + 8 = 117 10 + 6 = 416 15 + 3 = 1218 Be the first to get the right answers!
The weather on any given day in a particular city can be sunny, cloudy, or rainy. It has been observed to be predictable largely on the basis of the weather on the previous day. Specfically: • if it is sunny on one day, it will be sunny the next day 3/10 of the time, and be cloudy the next day 1/2 of the time • if it is cloudy on one day, it will be sunny the next day 3/10...

Every day rainfall (in mm) in the world's most rainy place, Mawsynram (India), is normally distributed with o = 0.2 cm. The mean rainfall on a random sample of 50 days is x = 4.05 cm. a. (7 points) Is there evidence to support the claim that the mean rainfall exceeds 4 cm? Use a = 0.05. (Show the 7-step procedure of hypothesis testing) b. (2 points) At what significance level will the null hypothesis be rejected in part (a)?...
