The incubation period refers to the number of days between being in contact with an infected person and actually showing symptoms of being infected. Health care professionals say that the mean incubation period of COVID-19 is 12 days with a standard deviation of 2 days. This accounts for the 14-day quarantine period. With the recent upsurge of infections due to the different variants of the virus, a group of researchers surveyed 100 confirmed cases and found that the mean incubation period is 11.5 days.

![The incubation period refers to the number of days between being in contact with an infected person
and actually showing symptoms of being infected. Health care professionals say that the mean
incubation period of COVID-19 is 12 days with a standard deviation of 2 days. This accounts for the
14-day quarantine period.
With the recent upsurge of infections due to the different variants of the virus, a group of researchers
surveyed 100 confirmed cases and found that the mean incubation period is 11.5 days. Is there enough
evidence to show that the mean incubation period has actually changed?
