Question 7 3 pts The random vanable x is known to be uniformly distributed between 5 and 18. Compute the standard deviation of x. 2.887 O 8.333 3.75 3,56 D Question 8 3 pts The random variable is the number of occurrences of an event over an interval of 10 minutes. It can be assumed that the probability of an occurrence is the same in any two time periods of an equal length. It is known that the mean number of occurrences in 10 minutes is 6.3. What is the probability of exactly 8 occurrences in 20 minutes? o 2256 0.1537 0.0531 0.0351
