Suppose researchers use a cutoff of p < 0.05 before they declare a result “statistically significant”. If 30 scientists independently conduct 22 studies each into the effect of Xon Y , how many studies—just through type I error alone—would we expect to have statistically significant results (and be published)?

Confidence in banks: A news poll conducted in 2012 asked a random sample of 1268 adults in the United States how much confidence they had in banks and other financial institutions. A total of 144 adults said that they had a great deal of confidence. An economist claims that less than 11% of U.S. adults have a great deal of confidence in banks. Can you conclude that the economist's claim is true? Use both...
