A new electric scooter company Maxwell Scooters' opened a retail shop in La Jolla recently and 300 UCSD students bought new scooters for getting around campus. After 8 students start complaining their scooters are faulty, negative on-line reviews for the scooters start to spread. In response, the scooter company adamantly claims that 99% of their scooters come off the production line working property. You think this seems unlikely and decide to investigate Select a significance level for you investigation. (Not to be turned in) What are reasonable choices for the Null Hypothesis for your investigation? Select all that apply. 1. The scooter company produces scooters that are 99% non-faulty.
2. The scooter company produces scooters that are less than 99% non-faulty.
3. The scooter company produces scooters that are at least 1% faulty.
4. The scooter company produces scooters that are -2.6% faulty. Return your answer in a function null_hypoth that takes zero arguments,
⢠Create a function simulate null simulates a single step of data generation under the null hypothesis. The function should return a binary array
⢠Create a function estimate_p_val that takes in a number N and returns the estimated p-value of your investigation upon simulating the nu hypothesis N times.
Note: Plot the Null distribution and your observed statistic to check your work.
