. Which of the following is not true about Bayesian probability theory?

Probabilities are seen as representing states of knowledge, or degrees of belief.

All probabilities are conditional on the assumptions made and the information used.

Bayesian analysis and conventional statistics usually lead to different conclusions.

Bayesian ideas predate the development of frequentist, or conventional, statistics.

It is a symmetric, Gaussian, function.

Its mean and mode are not the same.

It has a full width at half maximum of around 2.35 times its standard deviation.

Many commonly used probability distributions can be approximated by it in the limit of large numbers.
