DBTI’s leadership is looking at a wide variety of sample-based statistics to determine whether it
is safe to resume limited in-person learning. Their null hypothesis is that the rate of COVID-19
infection is no decreasing. Which of the following is an example of a Type II error? (select one)
a. Concluding that the rate of infection is dropping when it is not dropping.
b. Concluding that the rate of infection is not dropping when it is dropping.
c. Concluding that the sample is small and the data are skewed in a way that prohibits us
from using a normal distribution or a t-distribution in our analysis.
d. Concluding that the sample data are biased because only symptomatic infections tend
to be reported, and other testing shows a significant number of asymptomatic
infections.
