A website design company states "Of all Internet advertisers in the US, 26% are from retail services, 18% are from financial services, 15% are from web media, and the 41% can be categorized as other".

(3 pts) Specify null and alternate hypotheses (Ho and Ha) b. (7 pts) Perform the appropriate test at alpha = . 10c. [2 pts] Circle one: i. Reject Ho ii. Fail to reject Ho d. [4 pts] Circle the best interpretation of the test results: i. the distribution of US Internet advertisers is as claim ed. ii. the distribution of US Internet advertisers is not as claimed iii. There is a 90% probability that the distribution of US Internet advertisers is as claimed. however due to sampling error, there is also a 'ittl probability that it is not as claimed. iv. There is a 90% probability that the distribution of US Internet advertisers is not as claimed, however due to sampling error, there is also a 10% probability that it is as claimed. During a clinical trial of a own; for pain relief, subjects received either a placebo or the drug. and the results were recorded in this table. You need to determine if results are dependent on treatment. Pain Relief Results No Pain Relief [2 pts] Specify null and alternate hypotheses {Ho and Ha} [5 pts] Eielow, fill in the frequencies you would expect if result and treatment are independent: Pain Relief Results No Pain Relief C. {5 pts} at d=_Ei1, perform the appropriate test. d. {2 pts} Circle one: i. Reject Ho ii. Fail to reject Ho e. [4 pts] Conclusion: {circle one} i. Results are independent of treatment. ii. Results are dependent on treatment. iii. There is a 99% probability.r that results are independent of treatment. However due to sampling error. there is also a 1% probability that results are dependent on treatment. iv. There is a 99% probabilityr that results are dependent on treatment. However due to sampling error, there is also a 1% probability that results are independent of treatment
