As you know the answer already I don't think you need any further explanation :)
The one that doesn’t go through the origin
Answer:

Step-by-step explanation:
From the question we are told that:
Data

Generally the equation for Point estimate
is mathematically given by




Roughly 1.7 percent of the bands are shorter than 3cm. We calculate the z score of the data point in standard distribution. By definition of z score, we use score minus mean divided by standard deviation. z=(3-6)/1.5=-2. A z score of -2 corresponds to approximately 1.7%, in other words, roughly 1.7 percent of data is less than 3cm.
