The actual amount of water dispensed to individual bottles is Normal in distribution. During a quality control inspection, 12 bottles were selected randomly, and their water volumes carefully measured. The 12 bottles measured had a mean volume of 496 ml with standard deviation 6.12 ml. The quality control inspectors are testing to see if they can conclude that the mean volume of water in all bottles produced by this factory is different from 500 ml. Which of the following is closest to the p-value they obtain based on this sample?
Questiоns 18-20 refer tо the fоllowing scenаrio: A compаny clаimed that 90% of customers are satisfied with customer service. Somebody suspects that the actual proportion satisfied is lower than 90%. A random sample of 100 of the company's customers found 85 that were satisfied with customer service. Define p to be true proportion of customers that are satisfied with service.
