According to Wikipedia, "The humidex (short for humidity index) is an index number used by Canadian meteorologists to describe t of 2 how hot the weather feels to the average person, by combining the effect of heat and humidity." A meteorologist (named April) found the humidex in Edmonton for the month of August follows a uniform distribution between 36.5 and 42.5. a. Randomly and independently selecting 50 humidex values from previous August months in Edmonton, what is the probability that the sample mean is greater than 39.3? 0.4667 O0.2061 O 0.4522 31 O 0.7939 0.5478 Fini Tim b. Refer to the previous question. Suppose another meteorologist (named May) believes the humidex in Edmonton for the month of August is normally distributed with a standard deviation of 2.018. Randomly and independently selecting 25 humidex values from previous August months in Edmonton and based on May's belief, what can be said about the sampling distribution of the sample mean of humidex? It is normal with a standard deviation of 0.404. O It may not be normal with a standard deviation of 2.018. It may not be normal with a standard deviation of 0.404. It may not be normal because the Central Limit Theorem requires n to be at least 30. " It is normal with a standard deviation of 2.018
