A 56-year-old male patient presents to the Primary Care clinic to establish care and states that he has not seen a medical provider in over 25 years.  The patient is currently without complaints.  Routine laboratory studies are ordered, including a comprehensive metabolic panel, CBC, and fasting lipid profile.  The laboratory reports the appearance of white, opaque serum (see image below) when analyzing the patient’s blood, and the physical examination was notable for the presence of multiple xanthomas over the back, proximal extremities, and chest area.  Based on this information, which of the following laboratory results would you expect to find in this patient?                                                              

A 42-year-old male presents to the emergency department due to acute onset of fever, malaise, and generalized arthralgias. His social history is pertinent for chronic use of marijuana and heroin. He was also recently laid off at his job and has been on what he calls a “drug binge.” The emergency room physician does a thorough examination and hears a high-pitched holosystolic murmur along left lower sternal border.  The emergency room staff begin running a number of labs and diagnostic tests based on the clinical suspicion that he may have infective endocarditis.  In a patient with a history of intravenous drug abuse (IVDA) and infective endocarditis, what is the most common causative bacterial pathogen and what is the most common heart valve affected?

Two researchers perform two different hypothesis tests.   Researcher A obtained a p-value of 0.03. Researcher B obtained a p-value of 0.15 Based on this information, the p-value from researcher [answer1] provides stronger evidence against the null and in favor of the alternative.  Use a significance level of 0.05. Researcher A should [answer2] the null hypothesis. Researcher B should [answer3] the null hypothesis.

Suppose a researcher randomly sampled 980 current college students in Pennsylvania. From this random sample, when separated by sex, the researcher found males spent on average $3,400 on food per year, compared to females who spent on average of $3,000 on food per year. The population of interest is [answer2]. The corresponding parameter symbol is [answer1].  The best estimate for the parameter is [answer3]=$[answer4] Since this survey used [answer5], we [answer6] generalize our findings to the population of interest

A large intro class of two thousand students did a bead box activity to estimate the proportion of blue beads in a very large box of beads.  Each student took a random sample of size 100 and recorded their sample proportion for the color blue.  A dotplot of these 2000 proportions is found below. Your sample proportion was 0.72.   Based on the sampling distribution found above, which of the below options is closest to the true population proportion of blue beads in the box?

Researchers were interested in the correlation between the minutes spent at the lunch table and amount of calories consumed for children who are in first grade. They sampled n = 18 first grade children where they found the sample correlation to be r = -0.65, with a margin of error = 0.12. What is the correct calculation for the interval estimate for the population correlation? [answer1]
