Time Complexity

In computer science, the computational complexity that is measured in terms of time is referred to as time complexity that defines how long it takes a computer to execute an algorithm. An algorithm's time complexity is measured by the the amount of time required to execute each statement of code in the algorithm. If a statement is set to execute repetitively, the number of times it will be N multiplied by the time it takes to run that function each time is equal .

Question

**Quality Control Experiment: Bolt Length Testing**

A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than 13 centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of 54 bolts. The sample mean bolt length was 13.05 centimeters. The population standard deviation is known to be \( \sigma = 0.18 \) centimeters.

**Questions:**

1. **What is the test statistic \( z \)?**
- Example: 1.23

2. **What is the \( p \)-value?**
- Example: 0.123

3. **Does sufficient evidence exist that the length of bolts is actually greater than the mean value at a significance level of \( \alpha = 0.01 \)?**
- Options to select from.
