1 ### Supercavitation and its Impact on Undersea Vehicle Speed#### OverviewSupercavitation is a propulsion technology for undersea vehicles that significantly increases their speed. Supercavitation occurs at speeds above approximately 50 meters per second when the pressure drops off sufficiently to allow water to turn into water vapor, forming a gas bubble behind the vehicle. When the gas bubble completely encompasses the vehicle, supercavitation is said to happen. In an experiment to observe this phenomenon, eight ( \( n = 8 \) ) tests were conducted on a scale model of an undersea vehicle in a towing basin. The average observed speed was \( \bar{x} = 102.2 \) meters per second, with the speed normally distributed and \( \sigma = 4 \) meters per second. The significance level \( \alpha \) is set to 0.05.#### Problem Statement(a) **Hypothesis Testing**- **Null Hypothesis ( \( H_0 \) ):** \( \mu = 100 \)- **Alternative Hypothesis ( \( H_1 \) ):** \( \mu < 100 \)(b) **Power of the Test**Compute the power of this test if the true mean speed is as low as 95 meters per second. Provide your answer rounded to four decimal places (e.g., 98.7654).(c) **Sample Size Calculation**Determine the sample size required to detect a true mean speed as low as 92 meters per second with a power of at least 0.85.#### Additional Resources- **Statistical Tables and Charts**- **eTextbook and Media**Note: Information icons next to problem parts (b) and (c) likely provide further details or hints for solving the problems. ---This exercise covers key statistical concepts such as hypothesis testing, computing the power of a test, and determining sample size for specified power. Understanding the application of these concepts to real-world scenarios, such as supercavitation, helps in grasping the impact and utility of statistics in scientific research and engineering.
