We believe that the percentage of our company fleet cars that will pass inspection is 80%. We decide to run a test to see if it is 80% or if it isn't. We sample 20 cars and find that 17 will pass. What's the conclusion from our test at a 10% alpha level? ail to reject and conclude that p > 0.8 onclusive, since the experiment doesn't meet normality requirements t and conclude that p < 0.8 reject and conclude that p = 0.8 he null and state that p=98

Transcribed Image Text:**Hypothesis Testing Example**
We believe that the percentage of our company fleet cars that will pass inspection is 80%. We decide to run a test to see if it is 80% or if it isn’t. We sample 20 cars and find that 17 will pass.
**What's the conclusion from our test at a 10% alpha level?**
- ○ Fail to reject and conclude that p > 0.8
- ○ Inconclusive, since the experiment doesn’t meet normality requirements
- ○ Reject and conclude that p < 0.8
- ○ Fail to reject and conclude that p = 0.8
- ○ Accept the null and state that p = 0.8
**Explanation:**
This exercise examines the hypothesis regarding the proportion of cars passing inspection. A statistical test is conducted with a 10% significance level to determine whether the hypothesized rate of 80% is valid based on the sample of 20 cars. The conclusion involves choosing one of the provided options based on statistical analysis results.
