Help me to answer all the given problems below, Statistics and Probability Tutorsss...

I.

Activity '- Chock It Out! Directions: Read and analyze each problem. On the table below, put a check on the columns of the criteria that correspond to the given problem. 1. Uber company.r claims that the mean time to rent a car on their app is 60 seconds with a standard deviation of 30 seconds. A random sample of 36 customers attempted to rent a car on the app. The mean time of renling was 75 seconds. Is this enough evidence to contradict the company's claim? 2. The wailing time to be seated at the restaurant has population standard devialion of 1G minutes. An expensive restaurant claims that the average waiting lime for dinner is approximately 1 hour, but we suspect that this claim is inated to make the restaurant appear more exclusive and successful. A random sample of 30 customers yielded a sample average wailing lime of 5D minutes. l-___-- Activity : Mark My Numbers! 1. Mabunga Elementary School has 1,000 students. The principal of the school thinks that the average IQ of students at Mabunga is at least 110. To prove her point, she administers an IQ test to 20 randomly selected students. Among the sampled students, the average IQ is 108 with a standard deviation of 10. 2. A new energy-efficient lawn mower engine was developed by a well-known inventor. He claims that the engine will run continuously for 5 hours on a single gallon of regular gasoline. From his stock of 2,000 engines, the inventor selects a simple random sample of 50 engines for testing. The engines run for an average of 295 minutes with a standard deviation of 20 minutes.Activity . Which is Which? Directions: Identify the appropriate test statistic to be used in each problem. Write ztest or t-test on a separate sheet of paper. 1. The CEO of a battery manufacturing companyr claimed that their batteries would last an average of 23D hours under normal use. A researcher randomly selected 2D batteries from the production line and tested them. The tested batteries had a mean life span of 250 hours with a standard deviation of 4D hours. Do we have enough evidence to suggest that the claim of an average of 230 hours is false?I 2. It was known that the number of tickets purchased by students at the ticket window for the volleyball match of two popular universities followed a distribution that has mean of EDD and standard deviation of 8.9. Suppose that a few hours before the start of one of these matches, there are IUD eager students standing in line to purchase tickets. Ifthere are 25G tickets remaining, what is the probability that all 10D students will be able to purchase the tickets they want
