An engineer wants to obtain a random sample of the output from a process manufacturing digital cameras. The process operates 16 hours per day, five days per week. She selects five cameras on Monday, Tuesday and Wednesday at random between 3pm and 4pm each day. This is an example of

Non-Random Sample

Step-by-step explanation:

A sample in which each element has an equal chance of being selected is known as a random sample. Otherwise, a sample is said to be a non - random sample.

An engineer selects five cameras on Monday, Tuesday, and Wednesday at random between 3 pm and 4 pm each day. So, the cameras that are not in the process of production between 3 pm and 4 pm have no chances of being selected.

So, each camera does not have an equal chance of being selected.

This is an example of a non - random sample.

answer: do we write it

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
