Step-by-step explanation:
Creating a table with the information will help us.
<6h of sleep - 75% reported tired | 25% reported ok
>6h of sleep - 70% reported ok | 30% reported tired
80% of all interns received <6h of sleep
Let's imagine that we have 100 interns at this hospital
<6h | >6h Total
Tired 75% of 80 30% of 20
ok 25% of 80 70% of 20
Total 80 | 20 100
<6h | >6h Total
Tired | 60 | 6 66
ok | 20 | 14 34
Total | 80 | 20 100
what percent of the interns report no feelings of tiredness during their shifts?
34/100 = 34%
