A two sample ttest for a dfference in means will be conducted to investigate mean gasoline prices in two states. From each state, 45 gasoline stations will be selected at random On the same day, the price of segular gasoline will be recorded for each nelected station and the sample mean price for each state will be calculated Have all conditions for inference been met? Yes, all conditions have been met. No, the data are not collected using a random method No, the sample sizeu are greater than 10 percent of the population D No, the sample aizes are not large enough to assume the sampling distribution is approximately normal No, the distributions of the sample data are not upproximately nomal
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 terms of global or local range. The definition of minimization in the thesaurus is the process of reducing something to a small amount, value, or position. Minimization (noun) is an instance of belittling or disparagement.
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 one would be easier? Walking on the road would be much easier than climbing a mountain.
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 first derivative test and second derivative test to understand the concave behavior of the function.

![A two sample ttest for a difference in means will be conducted to investigate mean gasoline prices in two states. From each state, 45 gasoline stations will be selected at random
On the same day, the price of regular gasoline will be recorded for each selected station and the sample mean price for each state will be calculated
Have all conditions for inference been met?
A Ves, all conditions have been met.
No, the data are not collected using a random method
c No, the sample sizes are greater than 10 percent of the population
No, the sample sizes are not large enough to assume the sampling distribution is approximately normal
No, the distributions of the sample data are not approximately normal.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbf4c0131-7fce-452c-8373-718ab77e8b04%2F93de23c7-403b-4a4e-a67c-3479a6496329%2Fhjn11f_processed.jpeg&w=3840&q=75)
