Answer :
Since type I error is to reject the null hypothesis when null is true
Correct option is:
The researchers think that greater than or less than 65% of college students will graduate with debt when, in fact, 65% will graduate with debt.
The null hypothesis is true if the experimental result matches the predicted theoretical result. The null hypothesis is disproved and we examine an alternative one if there are any variations in the observed parameters between the samples. The null hypothesis was rejected, which opens the door for additional study but does not imply that the first experimentation was flawed. Usually, the null hypothesis is used to gauge the strength of the evidence.
Hence we get the required answer.
