Need help with statistic problems? ANOVA assumes equal variances within each treatment. A) True B) False 2 Comparison of c means in one-factor ANOVA is the same as using c repeated t-tests. A) True B) False 3 Hartley's test measures the equality of the means for several groups. A) True B) False 4 If you have 4 factors (call them A, B, C and D) in an ANOVA experiment with replication you could have 4 different two-factor interactions. A) True B) False 5 Use the following scenario to answer questions 5 to 12. Sound engineers studied factors that might affect the output (in decibels) of a rock concert speaker system. The desired level of significance was α = .05. The results of their ANOVA tests are shown.The number of positions tested was A) 1 B) 2 C) 3 D) 4 6 The number of amplifiers tested was A) 1 B) 2 C) 3 D) 4 E) 24 7 The number of observations was A) 16 B) 19 C) 23 D) 24 8 The number of observations per cell was A) 1 B) 2 C) 3 D) 4 9 The effect of amplifier was A) significant. B) insignificant. C) borderline. 10 The effect of position was A) significant. B) insignificant. C) borderline. 11 The F statistic for amplifier was A) 10.16 B) 9.90 C) 5.72 12 The interaction was A) significant. B) insignificant. C) borderline. Use the following scenario to answer questions 13 to 15. Three randomly-chosen pieces of four types of PVC pipe of equal wall thickness are tested to failure to determine the burst strength (in pounds per square inch) under three temperature conditions, yielding the results shown below. 13 Which test would be appropriate? A) two-factor ANOVA with replication. B) one-factor ANOVA. C) dependent (paired samples) t-test. D) two-factor ANOVA no replication. 14 Total degrees of freedom would be A) 19 B) 12 C) 35 D) 59 15 An interaction test would be appropriate. A) True. B) False Optional Information: State/Country relating to Question: United StatesAlready Tried: I am in need of help don't know statistics
Optional Information: Level/Year: junior Subject: Statistics Already Tried: ANOVA questions
Do you still need help with these problems?Let me know.Thanks
Yes I do Please!!

Table is missing for question 5 and 13.Please send data table.Thanks
It"s Formatted can you see what You can help me with Now?
There should be two ANOVA tables for question 5 and 13. I need those table to answer questions from 5 to 15.Please send ASAP.Thanks
Source of variation ss df MS F P-value
Amplifier 99.02344 99.02344 0.0005718

Thanks for the infoCan you please send another table as well?Thanks
