A full-time food delivery driver notices that after they have a highly profitable morning, the DoorDash algorithm seems to “throttle” their account—deliberately sending them lower-paying orders for the rest of the day to average out earnings among all drivers. The driver knows that the historical, city-wide population mean payout for an individual order is $8.50. To test their theory, the driver records the payouts of a random sample of 19 orders received during the afternoon right after a highly profitable morning block. They found that the sample average for the afternoon was $7.82 with the standard deviation of $0.89. They want to see if their mean afternoon payout is significantly lower than the city baseline. Assume that the earnings are normally distributed. State H0 and Ha to test if the data provides sufficient evidence to conclude that their mean afternoon payout is significantly lower than the city baseline Check the conditions for the test Compute the following Estimated Standard Error (). Round to 4 decimal places. The observed value of the test statistics (). Round to one decimal place. Degree of Freedom for the test Find the p-value of the test. State your decision about H0 and Ha and explain how you made that decision. Use 5% level of significance. State your conclusion in the context of the problem. Were your suspicions correct?

Read Entire Instructions Before Attempting: Write a short essay of 1-3 paragraphs (i.e. 50-150 words) in response to the question below the line. It must be a free-standing short essay, not a short answer. One good way to tell the difference is that a short essay makes sense without the question. It will be almost impossible to answer this question well in less than 50 words. The quality of your writing (e.g. usage, grammar, spelling, etc.) will count. You are not required to cite Feser or my lecture for this short essay. Remember Generative AI is not allowed and using it will result in no credit for the entire exam. A second use will result in failure for the course. In your own words, explain the difference between a linear and hierarchical (causally ordered) series and give your own example of each one. (You should quote from Feser, but your examples must be your own. You cannot give the examples from our author or the the lecture–e.g. family tree, dominoes, etc. You will not receive credit for examples given in the text or lecture; they must be your own.)
