here total number of observations N =4*10=40
| Source | SS | df | MS | F |
| treatment | 25.5 | 3 | 8.5 | 1.71 |
| error | 179.1 | 36 | 4.975 | |
| total | 204.6 | 39 |
therefore incorrect option is: the total N =10 and F-statistics =0.8248

Questions 4 - 12 Refer to the following scenario. Due to the recent COVID-19 pandemic, researchers have been working tirelessly looking for treatments to aid the sick. Two groups of 21 patients (total N = 42) volunteered to receive treatment in a controlled hospital environment. They observed the effectiveness of the treatment drug hydroxychloroquine (Drug H) versus a Japanese pharmaceutical called favipiravir (Drug F). The researchers measured the percent of effectiveness (ranging from 0-100) across the patients after one week...
