(a) To determine To calculate: The critical numbers for the provided function f ( x ) = 1 3 x 3 − x 2 − 15 x + 6 . Explanation Given: The function is: f ( x ) = 1 3 x 3 − x 2 − 15 x + 6 Formula used: The critical number ( c ) is that number at which function f ( c ) is defined and either f ' ( c ) = 0 or f ' ( c ) doesn’t exist. And If f ( x ) = x n then; f ′ ( x ) = n x n − 1 Calculation: Consider the provided function, f ( x ) = 1 3 x 3 − x 2 − 15 x + 6 In order to find the critical numbers, calculate f ' ( x ) (b) To determine To calculate: The critical numbers for the provided function f ( x ) = 6 x 2 3 − 4 x .

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of tw…

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow compar…

3. Bayesian Inference – Updating Beliefs A medical test for a rare disease has the following characteristics: Sensitivity (true positive rate): 99% Specificity (true negative rate): 98% The disease occurs in 0.5% of the population. A patient receives a positive test result. Questions: a) Define the relevant events and use Bayes’ Theorem to compute the probability that the patient actually has the disease.b) Explain why the result might seem counterintuitive, despite the high sensitivity and specificity.c) Discuss how prior probabilities influence posterior beliefs in Bayesian inference.d) Suppose a second, independent test with the same accuracy is conducted and is also positive. Update the probability that the patient has the disease.
