In a test of a particular weight loss program, weights of 40 subjects are recorded before and ( point) after the program. The before-and-after weights result in a correlation coefficient of 0.876. Assuming a 0.05 significance level, find the critical values. Is there sufficient evidence to support the claim of a linear correlation between before-and-after weights? a. Critical values 0.312; there is sufficient evidence to support a claim of a linear correlation between before-and-after weights. b. Critical values 312; there is not sufficient evidence to support a claim of a linear correlation between before-and-after weights. c. Critical values +0.402; there is sufficient evidence to support a claim of a linear correlation between before-and-after weights. d. Critical values0.402, there is not sufficient evidence to support a claim of a linear correlation between before-and-after weights.

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
