Part II: Use 8 inference rules and 10 replacement rules (D.N., C.E., B.E., DeM. Dup., Assoc., Commu. Dist., Contrap. Export.) to prove the following arguments. You are NOT allowed to use C.P. or I.P. e) 1. X=T 2. ((QxT =R) =(XvW) 3. RD(XvT) 4. -(TvW) 1:Q
Anthony has just received Covid-19 test results from a patient named Melania. The accuracy of the test is as follows: the probability the test will be positive if Melania has Covid-19 is p, and the probability the test will be positive if Melania does not have Covid-19 is q. The proportion of the population that has Covid-19 is 7. The test comes back positive. Anthony has no information about Melania's symptoms. (For reasons he does not understand.) Problem 3c What value of y would result in the simple model of base-rate neglect we learned in class? 67 O 33 O 25 Question 24 Problem 3d If p = .95, q = .05, and r = .1, what must be the value of y if Anthony believes that the probability Melania has Covid-19 is .9?

More than 68% of workers indicate that they are mildly satisfied with their job. Express the null and alternative hypotheses in symbolic form for this claim (enter as a percentage).H0:pH1:pUse the following codes to enter the following symbols: ≥≥ enter >= ≤≤ enter <= ≠≠ enter !=
Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 68.85. You want to test this claim.The null and alternative hypothesis in symbols would be: H0:p≥68.85H1:p<68.85 H0:p≤68.85H1:p>68.85 H0:μ=68.85H1:μ≠68.85 H0:μ≤68.85H1:μ>68.85 H0:p=68.85H1:p≠68.85 H0:μ≥68.85H1:μ<68.85 The null hypothesis in words would be: The average of price of all textbooks from the store is less than $$ 68.85. The average of price of all textbooks from the store is greater than $$ 68.85. The average price of textbooks in a sample is $$ 68.85 The proportion of all textbooks from the store that are less than 68.85 is equal to 50% The average price of all textbooks from the store is $$ 68.85 Based on a sample of 90 textbooks at the store, you find an average of 67.05 and a standard deviation of 15.6.The point estimate is: (to 3 decimals)The 95 % confidence interval (use z*) is: ______ to _____(to 3…

The US justice system considers an accused person innocent until proven guilty and there has to be proof beyond a reasonable doubt to convict the accused. In recent years, several individuals have been released from prison because new DNA tests proved them innocent. When the court originally convicted them (falsely as it turns out): (check all that apply) a. They committed a type-II error b. They committed neither a type-I nor a type-II error c. They committed a type-I error d. They committed both a type-I and a type-II error

G is defined as this fair spinner landing on a multiple of 4. H is defined as the spinner landing on 11 or higher. What is P(G AND H)? Give your answer in decimal form.
83% of workers indicate that they are mildly dissatisfied with their job. A researcher feels this percentage has changed. Express the null and alternative hypotheses in symbolic form for this claim (enter as a percentage). Ho: H₁: Use the following codes to enter the following symbols: enter >= enter <= #enter !=
Determine whether to reject or fail to reject Ho at the level of significance of a) a = 0.09 and b) a = 0.02. Ho: H=127, Ha: 127, and P=0.0371. a) Do you reject or fail to reject Ho at the 0.09 level of significance? O A. Fail to reject Ho because P 0.09. O D. Fail to reject Ho because P>0.09. -C
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p= 0.74 versus H,: p#0.74 n= 500, x= 360, a = 0.05 Is npo (1- Po) 2 10? Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) O A. Yes, because npo (1- Po) O B. No, because npo (1- Po) =|
