Answer:
Step-by-step explanation:
Confidence interval is written in the form, sample mean ± margin of error
The sample mean is an estimator for the population mean. The confidence level is used to express how confident we are that the population mean is within the calculated confidence interval. The lower limit of the given confidence interval is 2.619 hours/day while the upper limit of the confidence interval is 3.401 hours/day
Therefore, the INVALID interpretations of the 95% confidence interval are
A. About 95% of all Cal Poly students spend between 2.619 and 3.401 hours/day watching TV.
B. There is a 95% chance that, on average, Cal Poly students spend between 2.619 and 3.401 hours/day watching TV.
D. In the long run, 95% of the sample means will be between 2.619 and 3.401 hours.
E. None of the above.

Solution:
Trigonometry defines relationship between the sides and angles of the triangle.
For any angle 
,
= side opposite to /side adjacent to
In ΔGHI,
Put 
So,
Therefore,
Answer:
The correct option is;
We cannot infer a cause and effect relationship because the multiple variables were included
Step-by-step explanation:
The criteria required in order to establish a cause and effect relationship includes the following;
1) There must be a temporal precedence between the cause and the effect such that the cause must take place before the effect
In the question, it is not clearly stated weather there was a divorce (the likely cause) takes place before the event
2) In the vent that the cause occurs, the effect must occur
Therefore, all those who are not married are expected to be deceased for there to be a cause and effect relationship
3) The cause and effect relationship must not be explicable by other factors
In the question, it is stated that those who were married were more likely to be active physically, maintain an healthy weight and were nonsmokers, which are factors that contribute to longevity.
