Find the mean and the standard deviation of the number of hours parked. (Round your intermediate values and final answers to 3 decimal places.)
No data given.
Find the mean first = sum of scores/number of scores
Subtract each of the scores from the mean and square each difference. Find the sum of these squares. Divide that by the number of scores to get variance.
Standard deviation = square root of variance
To find the mean and standard deviation of the number of hours parked, you would need to know the individual values of the number of hours parked for each instance.
Once you have the individual values, you can follow these steps:
1. Calculate the mean:
- Add up all the individual values of the number of hours parked.
- Divide the sum by the total number of instances.
- Round the result to 3 decimal places.
2. Calculate the variance:
- Subtract the mean from each individual value of the number of hours parked.
- Square each of the differences.
- Add up all the squared differences.
- Divide the sum by the total number of instances.
- Round the result to 3 decimal places.
3. Calculate the standard deviation:
- Take the square root of the variance calculated in step 2.
- Round the result to 3 decimal places.
Please provide the individual values of the number of hours parked so that I can follow the steps and calculate the mean and standard deviation for you.
