A plant in Alamo TN, manufactures complex transformer components that must meet specific guidelines for safety One such component is constructed to deliver 1,000 volts of electricity. A component creates a critical safety hazard if it absorbs humidity at a level above 3%. Any components that absorb too much humidity will be destroyed. A quality control inspector uses a random sample of components to conduct a hypothesis test with H o The humidity level absorbed is 3%, and Ha The humidity level absorbed is more than 3%. What is a Type l error in this context? A Type error would result in failing to reject a false null hypothesis. This means the company would believe the humidity level is at most 3%, when in fact it exceeds 3%. A Type I error would result in rejecting a true null hypothesis. This means the company would believe the humidity Wevel is more than 3%, when in fact it is not more than 3%. A Type 1 error would result in rejecting a true null hypothesis. This means the company would believe the voltage delivered is more than 1.000 volts, when the voltage is actually not more than 1,000 volts. A Type l error would result in failing to reject a false null hypothesis. This means the company would believe the voltage delivered is no more than 1,000 volts, when the voltage is more than 1,000 volts.

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
