F tаble.pdf 1. (5 pоints) Multiple-chоice questiоns: (1) For аnаlysis of variance, the term “two-way” refers to: (0.5 points) (A) The number of factors (B) The number of levels (C) The number of replications (D) The number of elements in each group (E) The number of combinations of factors (2) In a one-way ANOVA F test, “the among group” variation is attributable to: (0.5 points) (A) SS Treatment (B) SS Error (C) SS Total (D) SS Interaction (E) MSA/MSE (3) When the k population means are truly different from each other, it is likely that the average error deviation: (0.5 points) (A) is relatively large compared to the average treatment deviations (B) is relatively small compared to the average treatment deviations (C) is about equal to the average treatment deviation (D) none of the above (E) differ significantly between at least two of the populations (4) When conducting a one-way ANOVA, the the between-treatment variability is when compared to the within-treatment variability, the the value of FDATA will be tend to be. (0.5 points) (A) smaller, larger (B) smaller, smaller (C) larger, larger (D) smaller, more random (E) larger, more random (5) When conducting an ANOVA, FVALUE (CALCULATED ) will always fall within what range? (0.5 points) (A) between negative infinity and infinity (B) between 0 and 1 (C) between 0 and infinity (D) between 1 and infinity (6) If FDATA follows an F distribution with df1=4 and df2=5, what is the boundary value of F where P(FDATA < F) = 0.95? (0.5 points) (A) 0.05 (B) 5.19 (C) 6.25 (D) 15.52 (E) 11.39 (7) Suppose the critical region for a certain test of the null hypothesis is of the form F > 9.48773 and the computed value of F from the data is 1.86. Then choose the correct answer: (0.5 points) I: H0 should be rejected. II : The significance level is given by the area to the left of 9.48773 under the appropriate F distribution. III : The significance level is given by the area to the right of 9.48773 under the appropriate F distribution. IV : The hypothesis test is two-tailed V : Fail to reject H0 (A) I and II (B) I and III (C) I and III and IV (D) III and V (E) IV and V (8) Choose the correct option: (0.5 points) I: t-distribution is symmetric II : chi-square distribution is symmetric III : Standard normal distribution is symmetric IV : F-distribution is symmetric (A) Only I is correct (B) I and III are correct (C) Only IV is correct (D) I and IV are correct (8) An investigator randomly assigns 30 college students into three equal size study groups (early- morning, afternoon, late-night) to determine if the period of the day at which people study has an effect on their retention. The students live in a controlled environment for one week, on the third day of the experimental treatment is administered (study of predetermined material). On the seventh day the investigator tests for retention. In computing his ANOVA table, he sees that his MS within groups is larger than his MS between groups. What does this result indicate? (1 point) (A) An error in the calculations was made. (B) There was more than the expected amount of variability between groups. (C) There was more variability between subjects within the same group than there was between groups. (D) There should have been additional controls in the experiment. 2. (30 points) Let x1, x2, x3 be independent random variables that have normal distribution N(μi, σ2), i = 1, 2, 3. We shall test H0: μ1 = μ2 = μ3 against all alternatives on the basis of a random sample of size ni = 4 from each of the three distributions. The observed data are shown in table below. x1: 9 7 10 8 x2: 15 14 11 12 x3: 11 7 5 6 a. Clearly describe H0 and H1 b. Construct your one-way ANOVA table and state your conclusion (use α = 0.05) 3. (40 points) An evaluation of a new coating applied to 3 different materials was conducted at 2 different laboratories. Each laboratory tested 3 samples from each of the treated materials. The results are given in the next table: LAB(A) Materials (B) 1 2 3 1 4.1 3.1 3.5 3.9 2.8 3.2 4.3 3.3 3.6 2 2.7 1.9 2.7 3.1 2.2 2.3 2.6 2.3 2.5 Row and column sums: LAB(A) Material (B) 1 2 3 Total (Ai) 1 31.8 2 22.3 Total (Bj) 20.7 15.6 17.8 54.1 a. What is the number of factors? b. What is the number of levels for each factor? c. What is the number of replications? d. Test the hypotheses and state your conclusions for A, B, AB at α = 0.05. 4.

VRAAG 3 'n Bаl, A, wоrd vertikааl оpwaarts vanaf 'n hоogte, h, met 'n spoed van 15 m∙s-1 gegooi. OP DIESELFDE OOMBLIK word 'n tweede, identiese bal, B, vanaf dieselfde hoogte as bal A laat val soos in die diagram hieronder aangetoon. Beide balle ondergaan vryval en tref uiteindelik die grond. NEEM OPWAARTS AS POSITIEF. Regterklik op die onderstaande blou blokkie om die diagram in 'n nuwe venster oop te maak. 3.1 Wat beteken die term vryval. (2) 3.2 Bereken die tyd wat dit bal A neem om na sy beginpunt terug te keer. (4) 3.3 Bereken die afstand tussen bal A en bal B wanneer bal A op sy maksimum hoogte is. (7) 3.4 Skets 'n snelheid-tydgrafiek vir die beweging van bal A vanaf die tyd wat dit geprojekteer is totdat dit die grond tref. Toon die volgende duidelik op jou grafiek aan: • Die beginsnelheid • Die tyd wat dit neem om sy maksimum hoogte te bereik • Die tyd wat dit neem om na sy beginpunt terug te keer (4) [17]
