1. If you analyzed the outbreak of illness from eating at a local restaurant and you counted 185 individuals who became ill out of 245 who ate at the restaurant that day. Calculate the attack rate from eating at the restaurant.

2. You are a clinical epidemiologist. You tracked the health of 1,000 college students who ate at the Residence Dining Hall all 4 years from their freshman year through graduation in 2008 . You accurately found that 200 of the RDH diners developed metabolic syndrome while 20 were misdiagnosed as having metabolic syndrome when they really did not. Another 20 were misdiagnosed as not having it. The rest were correctly determined not to have it.

You repeated your study with another 1,000 college students at the same university in 2018. You accurately found that 400 of the RDH diners developed metabolic syndrome while 40 were misdiagnosed as having metabolic syndrome when they did not. Another 40 were misdiagnosed as not having it. The rest were correctly determined not to have it.

From the scenario above, what was the sensitivity in 2018?
