Software Upgrade A software company is trying to decide whether to produce an upgrade of one of its programs. Customers would have to pay $100 for the upgrade. For the upgrade to be profitable, the company must sell it to more than 20% of their customers. You contact a random sample of 60 customers and find that 16 would be willing to pay $100 for the upgrade. Do the sample data give convincing evidence that more than 20% of the company's customers are willing to purchase the upgrade? Carry out an appropriate test at the a=0.05 significance level. Which would be a more serious mistake in this setting-a Type I error or a Type II error?
