We wish to study the quality of our production line. We take a random sample of 1000 widgets from our line. A quality rating was

determined for each of the 1000 widgets, and the average quality rating in the sample was 4. The sample standard deviation was 0.5. Also, 6 of the 1000 widgets were found to be defective.
Estimate the average quality rating for widgets from our production line, and include the uncertainty in this estimate in the form, a ± b.

Rewrite this non-statistical question as a statistical question. How many minutes do I exercise each day?
stira [4]

Answer:

The statistical question should be

"how many minutes do I exercise on each day of the week" and "how many minutes do I exercise each day of the week whilst there is background music"

Step-by-step explanation:

Here we have the non statistical question, how many minutes do I exercise each day

We note that a statistical question is one in which there are are different variety answers, where the distribution and the inclination of the the answers is sought

Therefore, statistically, we should ask, "how many minutes do I exercise on each day of the week" or "how many minutes do I exercise each day of the week whilst there is background music".
