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.
This basically says all the steps ! If you have any questions just tell me :)
X - 14 = 52
move - 14 for + 14
x = 52 + 14
x = 66
