We obtained data from a hospital for the number of newborns for each hour in a day. Th total number of babies was 2880. A glance at the table below suggests that there is a certain concentration of newborns during the night and early morning hours. Is this tendency significant? Test the hypothesis that the hour of birth is uniformly distributed between 0 and 24 hours. Use the $x^2$ test at the significance level $\alpha$=0.05. Hour # of the newborn (Oi) 0 127 1 139 2 143 3 138 4 134 5 115 6 129 7 113 8 126 9 122 10 121 11 119 12 130 13 125 14 112 15 97 16 115 17 94 18 99 19 97 20 100 21 119 22 127 23 139 Total 2880

A sequence of code that operates on shared state. Multiple activities that can happen at the same time. An efficient way to check that N threads have finished their work. A type of synchronization variable with only two atomic operations, P() and V(). When a scheduler takes the processor away from one task and gives it to another. When a thread uses a lock to prevent concurrent access to a shared data structure. A thread spins in a loop waiting for a concurrent event to occur, consuming CPU cycles while it is waiting. A scheduling policy where the OS assigns threads to processors without knowledge of the intent of the parallel application. A way to increase concurrency by partitioning an object's state into different subsets each protected by a different lock. A scheduling policy for multiprocessors that performs all the runnable tasks for a particular process at the same time. An atomic read-modify-write instruction that reads a value from memory to a register and writes the value 1 to that memory location. An atomic read-modify-write instruction that first tests the value of a memory location, and if the value has not been changed, sets it to a new value.
