Solution :

A group of researchers mistakenly concludes from a poorly designed experiment that acetaminophen cures the common cold.

These researchers have committed the types of error is

d) Type I error

The type 1 errors occur when researchers reject the null hypothesis when they should not have. In other words, they

conclude a significant result when in actuality it does not exist. This is a particularly dangerous error to make,

as it could lead to the administration of an ineffective drug to patients in need of life-preserving treatment.
