Sorry if my concerns are kind of silly for you guys, but I just don't really understand the answers to questions 2 and 3. In my understanding, the answers to questions 2 and 3 must be like the ones below. If anyone has the same concerns or observes any errors in my understanding, please help me figure it out.

Question 2:
Y --> This yes is becauce the test as introduced must be conducted in a sound-attenuated room. So, does the "[color=#000000]major noise disturbance" affect the test result of Ramesh?[/color]
N
Y
Question 3:
T
T --> This true based on the introduction that those under 5 would suffer from "severe excessive daytime sleepiness" while those under 2 are " unlikely to be exaggerating a complaint of excessive daytime sleepiness, to suffer from fatigue rather than sleepiness", and there is just 1 person under 5 and greater than 2, which is Sara, right?

Hi TinoThai,

You've got the right instinct that noise matters and that the thresholds matter. Both slips come from one small detail each, so let me point to exactly where.

Q2, statement 1 - why it's No

You reasoned that noise in the sound-attenuated room would spoil Ramesh's test. The logic is fine - but check who was actually tested on 6/17.

- From the date column (Tab 3): Ramesh was tested on 6/16, not 6/17.
- The only patient tested on 6/17 was Sara.
- From Tab 2, Sara is already in the "could be misleading" group (prescription stimulant).

So the noise lands on a day when the only patient present was already flagged. Nobody moves from "not misleading" to "misleading." The question asks whether the status changes - and here nothing does. That's why it's No. (Ramesh isn't touched at all, because he wasn't there on 6/17.)

Q3, statement 2 - why it's False

Here's the exact trip-up: you treated "under 2 minutes" and "under 5 minutes" as two separate groups, so you put Ramesh (≈1.98) in the "under 2" box and left only Sara in the "severe" box.

But re-read Tab 1: "latencies shorter than 5 minutes are taken to indicate severe excessive daytime sleepiness." Being under 2 doesn't take you out of "under 5" - under 2 is inside under 5.

So both qualify as severe:
- Ramesh≈ 1.98 min - under 5
- Sara≈ 4.94 min - under 5

That's two patients, not one - statement is False.

Quick way to feel the nesting: "Everyone under 18 is a minor." A 9-year-old is under 10 - but that doesn't stop them from also being under 18. Under 2 minutes works the same way inside under 5.

Hope that clears both up!

Answer: No, No, Yes; True, False, True
