The data from a simple random sample with 25 observations was used to construct the plots given below. The normal probability plot that was constructed has a correlation coefficient of 0.940. Judge whether a t-interval could be constructed using the data in the sample.

The normal probability plot does not suggest the data could come from a normal population because 0.340 > 25 and the boxplot does not show outliers, so a t-interval could not be constructed.
(Round to three decimal places as needed.)
