Question

Which one of the following statements is true?
Select one:
O a. In large samples, there are not many
discrepancies between the outcomes of the
F test and the LM test
O b. Degrees of freedom of the unrestricted
model is necessary for using the LM test.
O c. The LM test can be used to test hypotheses
with single restrictions only and provides
inefficient results for multiple
restrictions
O d. The LM statistic is derived based on the
normality assumption

Which one of the following is a true biased
estimator of the error variance o?
Select one:
O a. o? = E(µ²)
O b. o? = n-1) D" =1 û¡ = SSR/n
O c. o² = n-1) E" =1 43 =
SS R/n
O d. o² = n¯1) E =1 (H; )² = SS R/n

A state-by-state survey found that the proportions of adults who are smokers in state A and state B were 22.9% and 19.3%, respectively. (Suppose the number of respondents from each state was 3000.) At a = 0.05, can you support the claim that the proportion of adults who are smokers is lower in state A than in state B? Assume the random samples are independent. Complete parts (a) through (e). (a) Identify the claim and state Ho and Ha. The claim is "the proportion of adults who are smokers in state A is the proportion of adults who are smokers in state B." Let p, and p2 be the two population proportions. State H, and Ha. Choose the correct answer below. O A. Ho: P1 = P2 Hạ: P1 # P2 O B. Ho: P1 P2 Ha: P1 SP2 D. Ho: P1 sP2 F.

Then each tube is cut open and the amount remaining is weighed, resulting in the following data: 0.51, 0.63, 0.42, 0.5, 0.35. Does it appear that the true average amount left is less than 10% of the advertised net contents? USE SALT (a) Check the validity of any assumptions necessary for testing the appropriate hypotheses.
