Iestion number $4$

If the random variable is normally distributed, its probability can be determined using any of the standard Normal table after standardizing the original variable. What is the mean and standard deviation of the standardized Normal variate?

In determining the area under the Normal curve using any of the given standard Normal table we usually rely on two main properties of the Normal curve. Mention these two properties.

i$.$ Less than $2500$g$?$

ii$.$ More than $3600g?$

iii. Between $4000g$ and $4500g?$
