1.12 It was noted in Section 1.2.1 that statisticians who follow the deFinetti school do not accept the Axiom of Countable Additivity, instead adhering to the Axiom of Finite Additivity. (a) Show that the Axiom of Countable Additivity implies Finite Additivity. (b) Although, by itself, the Axiom of Finite Additivity does not imply Countable Additivity, suppose we supplement it with the following. Let A₁ A₂ be an infinite sequence of nested sets whose limit is the empty set, which An D we denote by An 10. Consider the following: ... ... Axiom of Continuity: If An 10, then P(An) → 0. Prove that the Axiom of Continuity and the Axiom of Finite Additivity imply Countable Additivity.

Is the following a non-directional (two tailed) or directional (one tailed) hypothesis?  There are more students in the class who commute to campus than students who do not commute to campus?

3 4. 8 10 11 12) 13) K 12 Question 12 For a certain brand of tomato seeds, the seed package claims that it takes 87 days after planting for the tomato plants to produce fruit. Sarah, a botanist, wanted to know whether the mean number of days for the plants to produce fruit where she lives is different from 87 days. She planted 40 seeds and recorded the number of days for each plant to produce fruit. With all conditions for inference met, the hypothesis test was conducted at the significance level a = 0.05, and the test resulted in a pvalue of 0.0752. Which of the following is a correct conclusion? A Sarah has convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is greater than 87 days. B Sarah has convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days. Sarah does not have convincing statistical evidence to conclude that the population…

A. P (win/regular) = 0.82  P (win/prevent) = 0.64  Conclusion: You are more likely to win by playing prevent defense. B.  P (win/regular) = 0.33 P (win/prevent) = 0.67 Conclusion: You are more likely to win by playing prevent defense.  C.  P (win/regular) = 0.82  P (win/prevent) = 0.64  Conclusion: You are more likely to win by playing regular defense.  D.  P (win/regular) = 0.33 P (win/prevent) = 0.67 Conclusion: You are more likely to win by playing regular defense.

The average manufacturing work week in metropolitan Chattanooga was 40,1 hours last year. It is believed that the recession has led to a reduction in the average work week. To test the validity of this belief, the hypotheses are O* Họ 2 40.1 Hạ <40.1 ObHọ - 401 H * 40.1

These are the answer selections for the drop-down boxes.  The hypothesis test will be (two tailed, left-tailed, right-tailed) Reject the (alternative, null) hypothesis that the proportion of people who read books in print is (less than, equal to, greater than, not equal to) 0.25 in which case there is evidence (in support of, to reject) Do not reject the (null, alternative) hypothesis, in which case there is not enough evidence to (reject, support)the claim that the proportion of people who read books in print is not equal to 0.25.
