COVID-19 (novel corona virus) took the world by surprise in late 2019. By early 2020, nearly all countries worldwide were affected. Early reports from the US Centers for Disease Control and Prevention (CDC) estimated that approximately 1.7% of infected patients in the United States between the ages of 55 and 64 had died. This figure is known as the mortality rate of the virus for this age group. Suppose a sample of 1060 infected patients in the United States between the ages of 55 and 64 were randomly selected and 29 of the patients were known to have died. Use the p-value method to determine if the sample data support the conclusion that the mortality rate of patients between the ages of 55 and 64 is greater than 1.7%. Use a significance level of 5%. State the null and alternative hypothesis for this test. 0.017 Determine if this test is left-tailed right-tailed, or two -tailed. night-tailed two-tailed Oleft-tailed Should the standard normal () distribution or Student's (t) distribution be used for this test ?
