Concept explainers
To identify: the sample for analysis is biased or unbiased and type of sampling.

Answer to Problem 4GP
The sample of 52 students is biased and convenience sample and cannot be used to predict caramel in 600 boxes.
Explanation of Solution
Given information:
- Purpose of sampling is to determine type of popcorn sale.
- 52 students at lunch selected randomly.
The sampling data is considering only students that is a specific category. There might be adults in theaters and there choices of popcorn is not considered. This is the case of convenience sample.
Since the sample is convenience sample.sample , the above sample is baised sample and cannot be used to predict caramel in 600 boxes.

- Explain the conditions under which the Radius of Convergence of the Power Series is a "finite positive real number" r>0arrow_forwardThis means that when the Radius of Convergence of the Power Series is a "finite positive real number" r>0, then every point x of the Power Series on (-r, r) will absolutely converge (x ∈ (-r, r)). Moreover, every point x on the Power Series (-∞, -r)U(r, +∞) will diverge (|x| >r). Please explain it.arrow_forwardExplain the conditions under which Radious of Convergence of Power Series is infinite. Explain what will happen?arrow_forward

- Consider the function f(x) = x²-1. (a) Find the instantaneous rate of change of f(x) at x=1 using the definition of the derivative. Show all your steps clearly. (b) Sketch the graph of f(x) around x = 1. Draw the secant line passing through the points on the graph where x 1 and x-> 1+h (for a small positive value of h, illustrate conceptually). Then, draw the tangent line to the graph at x=1. Explain how the slope of the tangent line relates to the value you found in part (a). (c) In a few sentences, explain what the instantaneous rate of change of f(x) at x = 1 represents in the context of the graph of f(x).
