A mind reading experiment is done in which a subject tries to correctly identify which of 4 cards the researcher has randomly picked, where each card is equally likely. This is repeated for 200 trials. The null hypothesis is that the subject is guessing at random, while the alternative is that the subject can read minds and can guess the card selected at a rate higher than guessing at random. Which of the following would be a Type 2 error in this situation?

A new medicine is created to replace the old standard that has a success rate of 27% in treating a particular disease. Of the 350 people with the disease, 133, when treated, had a successful outcome. When testing to see if the new medicine has a better success rate, what is the correct null hypothesis?

Research Question: A certain species of prairie flower is reported to receive on average 12 different species of pollinators per hour. A researcher thinks the average is actually lower. A randomization distribution (based on 100 samples) has been created assuming the null hypothesis is true. To test this claim, the researcher finds 30 different plants of this species to observe and sets up cameras for each plant. After reviewing all of the footage captured over 1 hour, the reported sample average number of species to visit the prairie flowers is 10.8. Use all provided information to determine if there convincing evidence to suggest that the average number of pollinators to visit per hour is less than the 12 species. The sample mean provide convincing evidence that the average number of pollinators to visit is less than 12 because the p-value of is than 0.05.

A functional dexterity test was given to children of different ages where the time needed to complete the test was recorded in seconds when using the dominant hand. The test involved turning over 16 pegs as fast as possible when following a certain sequence. The data was used to obtain the Minitab output found below. Classify each statement below as true or false.
