7. In 2020, the COVID-19 pandemic created a huge problem globally. More than 2 million people died from this disease as of Jan. 15, 2021. Some people say the elderly people are more likely to be infected (Claim A), and the survivors are mostly younger (Claim B). We would like to take a case from a country to see if these claims are reliable. City B had few hundreds of COVID-19 infected cases in 2020, and we took the COVID-19 cases in Hospital C in this city for the calculation. These are the figures of the confirmed infected cases in C hospital: Survival cases' age: 65, 88, 23, 8, 45, 55, 32, 22, 42, 65, 51, 15, 27, 65, 34, 13, 25, 31, 58, 32, 45, 67, 30, 58, 74 Confirmed death cases' age: 90, 18, 43, 67, 88, 89, 28, 55, 32, 66, 42, 49, 76, 59, 63, 2, 60, 84 The questions are to follow:
e. We run an independent samples t-Test (alpha=0.05) to check whether age matters in the survival/death cases, the results are shown below. Please tell us your conclusion. (3 points)
