Extracted text: Ajanitor at a large office building believes that his supply of light bulbs has a defect rate that is higher than the defect rate stated by the manufacturer. The janitor's null hypothesis is that the supply of light bulbs has a manufacturer's defect rate of p= 0.09. He performs a test at a significance level of 0.01. The null and alternative hypothesis are as follows: Ho: p = 0.09 and Hạ p> 0.09. Choose the statement that best describes the significance level in the context of this scenario. O a. The defect rate we believe is the true defect rate. O b. The probability of concluding that the defect rate is equal to 0.09 when in fact it is greater than 0.09. Oc. The test statistic that we will use compare the observed outcome to the null hypothesis. O d. The probability of concluding the defect rate is more than 0.09 when it is equal to 0.09.
