A janitor 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. O c. The test statistic that we will use to compare the observed outcome to t null hypothesis. O d. The probability of concluding the defect rate is more than 0.09 when it is equal to 0.09.
