Answer:
First solve the inequality to determine the solution set. Solving the inequality we have



Then, the solution set is
. The solution is the interval
and it can be represented by the following graph.
Step-by-step explanation:
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:
2/60 I think
Step-by-step explanation:
A plane is 3 dimensional or 3D because it is not flat. The intersection of two planes would make an angle.
