QUESTION 5 1 points Save Answer The advertised claim for batteries for cell phones is set at 48 operating hours with proper charging procedures. A study of 5000 batteries is carried out and 15 stop operating prior to 48 hours. Do these experimental results support the claim that less than 0.2 percent of the company's batteries will fail during the advertised time period, with proper charging procedures? Use a hypothesis-testing procedure with $$ \alpha = 0.01 $$. What is your decision? don't reject $$ H_0 $$ reject $$ H_0 $$ don't reject $$ H_1 $$ reject $$ H_0 $$

Step 1
The claim is that less than 0.2 percent of the company's batteries will fail. Let p be the true proportion of batteries that fail. The claim can be written as $$ p < 0.002 $$. Since the alternative hypothesis ($$ H_1 $$) must contain the inequality, we set: $$ Show more…
