A patient is purchasing a home self-administered rapid COVID test with a sensitivity of 84% and a specificity of 99%. How is the sensitivity of this test interpreted?

Melatonin is compared to placebo for sleep in a single-group randomized cross-over study (n=328). Participants are randomized to receive melatonin or placebo for 3 months and then take the other agent for 3 months following a 1-week washout period. Which of the following tests would be most appropriate to determine if this is a statistically significant difference in mean sleep latency (i.e., mean minutes to fall asleep)?

A non-inferiority study compared risankizumab (intervention) to secukinumab (standard of care) for at least 90% improvement in plaque psoriasis symptoms. An NI margin of 12% was used. Risankizumab was found to achieve a 90% symptom improvement in 73.8% of patients and in secukinumab 65.6% of patients.  95%CI 0.8 to 38.8%). Which of the following is the best interpretation of these results. Compared to secukinumab:

Which of the following is a disease-oriented outcome?

Which of the following statements about stack and heap memory in Python is correct?

What is the charge on each of the capacitors Q1, Q2, Q3 corresponding to capacitor C1, C2, C3 in the figure? The potential difference of the battery is is 7.0 V.

A battery with EMF of 30 V and negligible internal resistance is connected to a resistor network as shown. Before the switch is closed, a current is delivered by the battery. After the switch is closed, a current is delivered by the battery. Find
