Step-by-step explanation:

Mark me the brainliest please

The weight of the bag is 1.5 standard deviations down the mean weight.

What is normal distribution?

'Normal distribution is a continuous probability distribution wherein values lie in a symmetrical fashion mostly situated around the mean.'

According to the given problem,

Mean weight (μ) = 4.10 ounces

Standard deviation (σ) = 0.10

Target weight (x) = 3.95

We know,

Z = ( x - μ ) / σ

   = (3.95 - 4.10) / 0.10

   = -1.5

Hence, we can conclude, the target weight is 1.5 standard deviations down.
