It is meant to mimic what may be found on \nthe AP Statistics Exam FRQs for inference type questions.\n\n* CURRENTLY ONLY WORKS FOR ONE SAMPLE Z TEST *\n\nTEST CASE:\nCOLLEGEBOARD 2021 QUESTION #4:\n\nThe manager of a large company that sells pet supplies online wants to increase sales by encouraging\nrepeat purchases. The manager believes that if past customers are offered $10 off their next purchase,\nmore than 40 percent of them will place an order. To investigate the belief, 90 customers who placed\nan order in the past year are selected at random. Each of the selected customers is sent an email with\na coupon for $10 off the next purchase if the order is placed within 30 days. Of those who receive the\ncoupons, 38 place an order. \n\nIs there convincing statistical evidence, at the significance level a = 0.05, that the manager's belief \nis correct? \n\nCopy + Paste: 1 2 1 y y 1 90 .05 .4 .422 x\n\nx = 30\nn = 90\na = 0.05\np = 0.4\nAll conditions are satisfied.\n\nOUTPUT: \n\nBecause 0.33 is greater than 0.05 there is convincing evidence that the alternate hypothesis is correct.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmandyschen%2Fstat-calculator","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmandyschen%2Fstat-calculator","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmandyschen%2Fstat-calculator/lists"}
