Samples of orders were taken at The Company to determine if the orders were recorded correctly for 30 days. 100 orders are inspected each day. The average proportion of orders with errors is p-bar = 0.2. Compute the Upper Control Limit for the p-chart.  

The temperature of ambient gas is 32ºC and has a potential humidity of 38 mg/L. What is the relative humidity if the actual humidity is 20 mg/L?

For patients diagnosed with Parkinson’s Disease, the following are common provoking factors for freezing of gait 

Consider the (5,k)-SAT problem: Input: A boolean formula in CNF form such that there are at most five literals in each clause, and an integer k ≥ 1.Output: An assignment of variables such that exactly k clauses are unsatisfied, or return NO if such an assignment does not exist. Prove that (5,k)-SAT is NP-complete.

The Largest Independent Set Problem is known to be in the class NP.

Let y_t=(y_(t-τ),…,y_(t-1)) be a vector of preceding spike counts up to but not including time t Let x_t=(x_(t-τ),…,x_(t-1)) represent the vector of preceding stimuli up to but not including time t. To mimic the refractory period in the GLM, if a spike occurs just prior to time t, the convolution of the spike occurrence with the post-spike filter h 

Match the pattern of spiking shown in A to D with the corresponding stimulus and postspike filters shown in 1 to 4

The figure shows a Venn diagram of two generic events A and B, where the event B is shaded to indicate that it is known to have occurred. If A and B are disjoint, then there are no outcomes of A contained in the event B.

Use this scenario to answer the next few questions: A 35-year-old male presents with shoulder pain after a fall while playing basketball. He reports pain on the lateral aspect of the shoulder, difficulty lifting his arm, and a feeling of instability. On examination, there is tenderness over the acromioclavicular (AC) joint, limited range of motion, and weakness in abduction.   Which structure is most likely injured given the patient’s history and symptoms?
