Maria solved the equation -5 1/8n = -9 3/4 . her answer was n = 1 37/41 . she is fairly confident about her answer, but wants to do a quick check of her solution using estimation.
which of the following shows a good check of her answer?

-6(2) = -12
-5(-2) = -10
-5(2) = -9
-5(2) = -10

The mean number of defective light bulbs per case produced during the morning shift.

Step-by-step explanation:

A parameter is a property that refers to a population, not a sample. The manager uses a random sample of 46 cases of light bulbs produced during a morning shift in order to estimate, with a significance level of 0.10, what is the  mean number of defective light bulbs per case produced during the morning shift. Since it is specified that the manager is interested in the morning shift, the parameter cannot be assumed for the production at the whole plant.
