are conditions for inference satisfied?

The conditions we need for inference on one proportion are: Random: The data needs to come from a random sample or randomized experiment. Normal: The sampling distribution of p^​p, with, hat, on top needs to be approximately normal — needs at least 10 expected successes and 10 expected failures.

['Null hypothesis (H0): A statement about the values of one or more population (sample) parameters, based on observation and prior knowledge.', 'Alternative hypothesis (Ha): A statement that contradicts the null hypothesis, based on observation and prior knowledge.']

Those are opinions that have to be proven before they become facts: what if the ditch doesn't work, or what it if was built for aesthetics or traffic safety and not for water control. The fact is that it is there. Inferences are based on analysis. They are statements of the unknown based on the known.

1 Answer. A hypothesis is the prediction about the outcome of an experiment. An inference is conclusion drawn based on observations and prior knowledge.

Consider 2 events A and B which satisfy the condition that they both are mutually exclusive and independent (simultaneously). Thus, if we chose any 2 events such that at least one of them is guaranteed to not occur, then those two events will be both mutually exclusive and independent.

An inference question asks students whether they understand the meaning of a piece of text that does not explicitly state it. It requires students of all ages to hone their deduction skills and practice their logical thinking.

A hypothesis can be defined as: A testable proposition.

['Hypothesis should be clear and precise. ... ', 'Hypothesis should be capable of being tested. ... ', 'Hypothesis should state relationship between variables, if it happens to be a relational hypothesis.', 'Hypothesis should be limited in scope and must be specific.']

['What are the issue and the conclusion?', 'What are the reasons?', 'What are the assumptions?', 'Are there any fallacies in the reasoning?', 'How good is the evidence?']

'Inference' is a noun and its meaning is the act or process of reaching a conclusion about something from known facts or evidence. ... 'Prediction' is also a noun. It means a statement about what will or might happen in the future. A 'prediction' generally is a verbal statement, but it can mean just a mental thought.

['Accurate: within its domain, consequences deducible from a theory should be in demonstrated agreement with the results of existing experiments and observations.', 'Consistent: internally (with itself) and with other currently accepted theories applicable to related aspects of nature.']

Inferential Statistics. Inferential statistics are often used to compare the differences between the treatment groups. Inferential statistics use measurements from the sample of subjects in the experiment to compare the treatment groups and make generalizations about the larger population of subjects.

['The hypothesis should be clear and precise so as to consider it to be reliable.', 'If the hypothesis is relational hypothesis, then it should be stating the relationship between variables.', 'The hypothesis must be specific and should have scope for conducting more tests.']

The purpose of statistical inference is to estimate this sample to sample variation or uncertainty.

Inductive reasoning does not guarantee a true result, but it does provide a means of making a conjecture. With deductive reasoning, we use general statements and apply them to spe- cific situations.

Your proposed "straightforward definition" of co-NP is wrong. For any problem A, we could pick V to be the procedure that ignores its arguments and immediately returns 1. Thus, by your definition, no problems would be in co-NP.
