Z score associated with sleeping 503 minutes = 0 minutes
Step-by-step explanation:
Given values of sleep per night for adults:
Mean value X = 503
Standard deviation σ = s
FInd:
Z score associated with sleeping 503 minutes
Computation:
⇒ P[X = 503]
⇒ P[(x - X) / σ] = [503 - 503] / s
⇒ Z score value = [0] / s
⇒ Z score value = 0
Z score associated with sleeping 503 minutes = 0 minutes
