An e-commerce research company claims that 60% or more graduate students have bought merchandise online. A consumer group is suspicious of the claim and thinks that the proportion is lower than 60%. A random sample of 80 graduate students shows that only 22 students have ever done so. Is there enough evidence to show that the true proportion is lower than 60%? Conduct the test at 10% Type I error rate State a consequence of committing a Type I error State a consequence of committing a Type II error Determine which error type has more serious consequences
