r items 12-15, refer to the problem below: Mr. Bautista asserts that fewer than 5% of the bulbs that he sells are defective. Suppose 100 bulbs are randomly selected, each are tested, and 2 defective bulbs are found. Does this provide sufficient evidence for Mr. Bautista that the fraction of defective bulbs is less than 0.05. Use a = 0.05. 12. What is the null and alternative hypothesis in the problem? A. Ho: p = 0.05 Ha:p# 0.05 B. Ho: p = 0.05 Ha:ps 0.05 C. Ho:p = 0.05 Haip<0.05 D. Ho:p = 0.05 Haip> 0.05 %3D 13. Compute the test statistic value. A. - 2.15 B. - 2.14 C. - 1.38 D. - 1.37 14. Determine the critical value. A. - 1.96 B. 1.96 C. - 1.645 D. 1.645 15. Base on the computed test statistic value and the critical value, is Mr. Bautista correct from his assertion that fewer than 5% of the bulbs that he sells are defective? A. Yes B. No C. Undecided D. Cannot be determined
