The standard normal curve shown below is a probability density carve for a
continuous random variable. This means that the area underneatkl the entire
curve is 1. What is the area of the shaded region between the two z-scores
indicated in the diagram?

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
