Answer: (a) There is a clear outlier in the data.
Step-by-step explanation:
The statement relates that sample= 24
Confidence interval= 80.2 to 89.8.
Now the data does not mention anywhere the standard deviation which is an important parameter in using the t-procedure rather we assume that standard deviation is not known. So, the most worrying part is the skewness and the presence of strong outliers in the t-procedure.
So, the option a) is correct meaning a clear outlier in the data.
