The following two hypotheses are tested:

Ho: The average body mass index of UF students is 25

Ha: The average body mass index of UF students is less than 25

Which of the situations below corresponds to a Type I error.

We conclude that the average body mass index of UF students is less than 25 when in fact it is 25.

We fail to conclude that the average body mass index of UF students is less than 25 when in fact it is less than 25.
