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.

Answer:
1.3889
Step-by-step explanation:
42*25.5=1,071
1,071/771.12=1.3889
20=-5-x
25=-x
-25=x
First, parentheses, distribute the negative
Then, add 5 to both sides
And finally, divide by -1 which give you the answer -25
