• A) 47.4^\(\circ\)C
• B) 49.4^\(\circ\)C
• C) 51.4^\(\circ\)C
• D) 53.4^\(\circ\)C
• E) None of the above

Definitions:

Type I Errors

False positive conclusions in statistical hypothesis testing, erroneously indicating that a novel effect exists.

Type II Errors

Occurs in hypothesis testing when the null hypothesis is falsely accepted, meaning that a real effect or difference is missed.

Sampling Distributions

The probability distribution of a statistic obtained from a large number of samples drawn from a specific population.

Statistical Significance

A measure of how likely it is that obtained results are not due to chance, often determined by a p-value.
