Answer:
The researcher concluded there was a relationship, but there isn't really one.
Step-by-step explanation:
We can say that the researcher made a type 1 mistake because the researcher concluded that there was a relationship, but it doesn't really exist. This premise defended by the researcher shows a false positive, where he assumed that the theses he made to approve the hypotheses of his study did not work, but the researcher did not realize and took the results as true. This type of error usually occurs when the test duration has not been respected and when the sample size has been set incorrectly.
