Please indicate if the following sentences are true or false. (Please do not mention the reason)

• In poisson distribution with quantity of 4.5 there is no probable event, because this distribution is related to discrete variables.

• The small sample random average with high probability is different with the population’s average.

• The population’s average is in anyway situated inside confidence interval for population’s average.

• Applying significance level 0.01 instead of 0.05 leads to decreasing both kinds of error.

• Increasing sample size leads to increasing the power of test.

Question

Please indicate if the following sentences are true or false. (Please do not mention the reason)

•	In poisson distribution with quantity of 4.5 there is no probable event, because this distribution is related to discrete variables.

•	The small sample random average with high probability is different with the population’s average.

•	The population’s average is in anyway situated inside confidence interval for population’s average.

•	Applying significance level 0.01 instead of 0.05 leads to decreasing both kinds of error.

•	Increasing sample size leads to increasing the power of test.

anonymous · Answer

•	When the curve slope of the power of the test is less, it is closer to ideal curve.

•	Student distribution chart is always shorter than normal curve and it becomes higher when degree of freedom increases.
