Hi priyalsethia,The trick to Question 2 is doing it in
two steps, and the question word that matters is
"change." It isn't asking whether the data is misleading; it's asking whether the new scenario would
flip any patient's status.
Step 1 - Lock each patient's current status (combine
Tab 2 patient data + the
Tab 3 note listing what makes results misleading: age under
16, noise, anxiety, atypical prior sleep, prescription stimulants/antidepressants):
-
Ramesh (34, no meds) -
not misleading-
Sara (prescription stimulant) -
misleading-
Angel (prescription antidepressant) -
misleading-
John (11, under 16) -
misleading-
Steve (54, only OTC supplements) -
not misleadingTest dates (Tab 3): Ramesh
6/16, Sara
6/17, Angel
6/18, John
6/20, Steve
6/21.
Step 2 - Check each scenario for a status flip:(1) Noise on 6/17. Only
Sara tested that day. But Sara is
already misleading because of her stimulant. Adding noise can't move someone who's already in the "misleading" group - and no one else was tested on
6/17. Nobody flips -
No.
(2) No one tested after 6/17 had anxiety. That's Angel, John, Steve. Anxiety was never claimed for them to begin with, so ruling it out removes nothing. Angel and John stay misleading (meds / age); Steve was already not misleading. No flip -
No.
(3) Everyone under 50 had atypical prior sleep. That's Ramesh (
34), Sara (
23), John (
11). Here's the key:
Ramesh was the only "not misleading" person in that group - atypical prior sleep now pushes him into "misleading." One status flips -
Yes.
So the answer is
No, No, Yes.
The insight to carry: a scenario only counts as a change if it moves someone
across the line. Anyone already misleading can't become "more" misleading, and a factor that was never in play can't be removed to matter.
Answer: No, No, Yespriyalsethia
