A computer manufacturing company produces 2 products: desktop computers and laptops. The quality controller wants to see if the proportion of defective desktop computers is higher than the proportion of defective laptops. To check this, he takes a random sample of 185 desktop computers and observes that 16 are defective and he also takes a random sample of 195 laptops and observes that 10 are defective. Assume a normal sampling distribution. Test an appropriate hypothesis and state your conclusion. Use a significance level of 0.01. (a) What are the null and alternative hypotheses? Ho: P 0.0 • НА: Р 0.0 • (b) What is the test statistic? (Round your answer to 2 decimal places, if needed.) (c) Using the statistical table, what is the p-value? (Round your answer to 4 decimal places, if needed.)
