To determine To explain: The difference between the point estimate and the interval estimate of μ Explanation Point estimate: Any statistic can be a point estimate which gives the estimated value for the parameter in the population. And these estimated values are single values which come from a set of sample data as an estimator for the population. Interval estimate: Interval estimate is the range of values of the statistic and the interval will contain the population parameter of the researcher’s interest with particular level of confidence. Difference between the point estimate and the interval estimate of μ : A single value obtained from point estimation on a set of sample data as a population mean for the population is the point estimate of μ

Minimization

In mathematics, traditional optimization problems are typically expressed in terms of minimization. When we talk about minimizing or maximizing a function, we refer to the maximum and minimum possible values of that function. This can be expressed in ter…

Maxima and Minima

The extreme points of a function are the maximum and the minimum points of the function. A maximum is attained when the function takes the maximum value and a minimum is attained when the function takes the minimum value.

Derivatives

A derivative means a change. Geometrically it can be represented as a line with some steepness. Imagine climbing a mountain which is very steep and 500 meters high. Is it easier to climb? Definitely not! Suppose walking on the road for 500 meters. Which …

Concavity

In calculus, concavity is a descriptor of mathematics that tells about the shape of the graph. It is the parameter that helps to estimate the maximum and minimum value of any of the functions and the concave nature using the graphical method. We use the …
