Always about the parameter only b. Always about the statistic only c. Always about both the statistic and the parameter d. Sometimes about the statistic and sometimes about the parameter - a. Always about the parameter only The probability of rejecting the null hypothesis when, in fact, the null hypothesis is true is called the Select one: a. significance level b. power of the test c. standard error d. p-value - a. significance level 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: H0 : p = 0.09 and Ha : p 0.09. Choose the statement that best describes the significance level in the context of the hypothesis test. Select one: a. The significance level of 0.01 is the probability of concluding the defect rate is more than 0.09 when it is equal to 0.09. b. The significance level of 0.01 is the z-statistic that we will use to compare the observed outcome to the null hypothesis. c. The significance level of 0.01 is the probability of concluding that the defect rate is equal to 0.09 when in fact it is greater than 0.09. d. The sig - a. The significance level of 0.01 is the probability of concluding the defect rate is more than 0.09 when it is equal to 0.09.
