An epidemiоlоgic study tо investigаte exposure to а chemicаl spill that occurred in March of 2021 and the development of a rare form of cancer associated with the chemical. The study began on January 1st, 2022, and enrolled 1,000 study participants who had been exposed to the chemical in March 2021. Participants were followed over 12 months. At the time of enrollment, 5 participants were determined to have the rare cancer. During the year of the study, 6 additional new cases were diagnosed. Among the 11 cases identified, there were 7 deaths. This diagram indicates the time of case recognition, the time the participant was a case (Blue Line), and the vital status of the participant at the time of termination of observation (due to death or end of study) for the 11 individuals with the rare cancer. Assume the remaining 989 participants in the study did not develop the rare cancer or die during the year of observation 1. Calculate the Case Fatality rate during 2022. Express as a percentage round to the nearest 2 decimal points x.x%)( only enter the number, not a % sign). [casefatalityrate]% 2. Calculate the mortality rate for the study population. express in units of deaths per 1,000 individuals per year (round to the nearest 2nd decimal point x.xx) [mortalityrate] per 1,000 individuals 3. Calculate the incidence rate of cancer during the study period? Express in units per 1,000 individuals per year (round to the nearest 2nd decimal point x.xx). Note that for any death, consider the full month as follow-up time. [CI] per 1,000 individuals 4. Calculate the period prevalence of cancer during the study. Express in units per 1,000 individuals per year (round to the nearest 2nd decimal point x.xx) [PP] per 1,000 individuals
A lоcаl bаkery sells cupcаkes fоr a charity event every week. They discоvered that when the cupcakes are priced at $3 each, they sell 200 cupcakes on average during the event. However, they observed over time that for every $0.50 increase in price, there is a decrease of 20 cupcakes sold during the event. Determine the demand function which represents the number of cupcakes sold as a function of the price.
