Henry caught a cold recently and therefore he has been sneezing a lot. His expected waiting time between sneezes is 35 seconds. The standard deviation of the waiting time between his sneezes is 1.5 seconds. Find a bound on the probability that the time between two consecutive sneezes is between 30 and 40 seconds. 2 3. In a study on eating habits, a particular participant averages 750 cm 3 of food per meal. a. It is extraordinarily rare for this participant to eat more than 1000 cm 3 of food at once.
