The reputation of many businesses can be severely damaged due to a large number of defective items during shipment. suppose 300
batteries are randomly selected from a large shipment; each is tested and 9 defective batteries are found. at a 0.1 level of significance, does this provide evidence that the proportion of defective batteries is less than 5%? what is the p-value for the test.
We are given with random samples = 300 batteries defective samples = 9 batteries level of significance = 0.1 Using the P-table values and using the given values, we see that the number of defective batteries are really less than 5%
