Question

Now assume that you have the test data for the battery capacity in an array. what is the standard deviation of the operating time? hint: use n = 20,000.

Answer 1

To find the standard deviation of the operating time, use the formula: Standard Deviation (σ) = √[Σ(x - μ)² / N]. Given the test data for battery capacity in an array, calculate the mean (μ) and use it to find the standard deviation (σ) using the formula.

Step-by-step explanation:

To find the standard deviation of the operating time, you can use the formula:

Standard Deviation (σ) = √[Σ(x - μ)² / N]

Where:

• x represents each individual battery capacity from the test data
• μ represents the mean battery capacity from the test data
• N represents the total number of batteries in the test data

Given that you have the test data for battery capacity in an array, you can calculate the mean (μ) and then use it to find the standard deviation (σ) using the formula.
