What is the z-score of a value that is 2.08 standard deviations greater than the mean?________ Express the answer as a decimal.
1 answer:
Is there something else to this question?
For example the numbers 45 and 20
There should be a dialogue question. Let's assume we gathered files and they were distributed with a mean of 45 minutes and a standard deviation of 12 minutes.
Now let's assume some random person had to wait less than 20minutes
Now to calculate the z-score we will use
This gives us a z-score of 2.08

Answer:
0.00998 Inches
Step-by-step explanation:
Thickness of the light bulb filament = 0.01 Inch
Allowable error = 2%.
2% of 0.01 = 0.02 X 0.01 =0.0002 Inch
Therefore, the allowable thickness of the bulb filament
We can then calculate the least allowable thickness of the filament as:
The least allowable thickness of the filament is 0.00998 Inches.
