Answer: 0%?
Step-by-step explanation: there isn't much to this problem because if it had a deviation of 3 from 68, it could be 7 digits from 65 to 71, but since 72 is out of the range, i can only say that this answer is not very correct if it has answer choices other than 0.
The probability is 0.160
'Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.'
mean (μ) = 68 inches
Standard Deviation (σ) = 3
We know,
Z = [tex]\frac{x - mean}{standard deviation}[/tex]
From the normal distribution bell curve, we can see that the percentage of students taller than 72 inches = 14% + 2%
= 16%
The probability that a randomly selected student will be taller than 72 inches = 16/100
= 4/25
= 0.16
= 16%
Hence, we can conclude, that the probability that a randomly selected student will be taller than 72 inches is 0.160
