FoEM CBR22- Cardiology Exam What underlying pathologic process distinguishes myocardial infarction from angina/unstable angina? Atherosclerotic plaque rupture → exposed endothelium → clot attaches → reduced blood flow; if cell death occurs (usually due to complete vascular obstruction) then positive trop and MI; if no cell death occurs then negative trop and angina/unstable angina. What is the difference between transmural and nontransmural infarction? Transmural: usually STEMI, la...

Definition of encryption - "Cryptography" -involves making and using codes to keep messages private and secure for their intended recipient --Kryptos = "hidden" Cryptanalysis - -involves cracking/breaking encrypted messages back into their unencrypted origins Bit Stream cipher - -encrypts plaintext one byte at a time (8-bits) -it is very fast encryption, lower hardware complexity, but can result in duplicate keystreams to encrypt and if someone gets both messages using the same key, t...

Alicia would like to know if there is a difference in the average price between two brands of shoes. She selected and analyzed a random sample of 40 different types of Brand A shoes and 33 different types of Brand B shoes. Alicia observes that the boxplot of the sample of Brand A shoe prices shows two outliers. Alicia wants to construct a confidence interval to estimate the difference in population means. Is the sampling distribution of the difference in sample means approximately normal? - Yes,...
