lesktop computers is higher than the proportion of defective laptops. To check this, he takes a random sample of 160 desktop computers and observes that 16 are defective and he also takes a random sample of 170 laptops and observes that 10 are defective. Assume a normal sampling distribution. Test an appropriate ypothesis and state your conclusion. Use a significance level of 0.05. a) What are the null and alternative hypotheses? Ho: p 0.0 HAi p = 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.) d) Based on the p-value, fail to reject + the null hypothesis.

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 160 desktop computers and observes that 16
are defective and he also takes a random sample of 170 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 0.05.
(a) What are the null and alternative hypotheses?
Ho: p
0.0
HẠ: p
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.)
(d) Based on the p-value, fail to reject + the null hypothesis.
