Multiples of 30 : 30,60,90,120,150....
and the first one that 4 goes into evenly is 60
The value of the slope increases and becomes closer to infinity
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.
8 percent of 84000 is 6720 add 2500 equals 9220
