50. A randomized block design the following sum of squares values: Total SS treatments must be A) 16 with 4 treatments without replicates and 5 blocks produced 1951, SST-349, SSE- 188. The value of F for B)742 C)115D)8.34 E) 13 51. Given the least squares regression line y 4.63 +1.38r, and a correlation of determination of 0.90, the coefficient determination must be A)-0.95 B)+0.95 6 C+1.38D)081 E) 081 $2. In a regression model involving 40 observations, the following estimated regression model was obrained: y- 135+41, +62x, +58,. For this model, the following stacistics are given: $SR -501 and SSE - 99. Tben, the coefficient of determination is: A) 0.198 B) 0.835 C1.00 D) 167 E) 0.914 53. In a chi-square goodness-of- fit test with 5 degrees of freedom and s significance level of a.o5, the chi-square value from the table is 11.070S. Which of the following computed values of the chi-square test statistic will lead to rejection of the null bypothesis? A).8.952 B).7.814 C).6.814 D). 17.61 E).0.25 54. To determine whether a single coin is fair, the coin was tossed 250 times, and heads was observed 140 times. The value of the test statistic is: A).3.6 B). 140 C. 110 D). 30 55. When you purchased a coin from super market and found there were 315 seeds showed purple and non-sweet, 155 seeds showed parpie and sweet, 135 seeds showed yellow and non- sweet, and 15 showed yellow and sweet Pleasse conductn X testing whether the data are fitting the Genatic law of Independent Assortment(gp-Su-: 3P-susu-3ppSu-1ppsusu) at Xa = 005-what are the value of X2 and conclusion? A) X.= 1327 and the data are fined the Genetic law of Independent Assortment (9P-Su-3P-susr 3ppSue 1ppsusu ) at Xa = 005 B) Xt= 5.327 and the dataare fitted the Genetic law of Independent Assortment (SP-Su-3P-susu: 3ppSu-:1ppsusu ) at Xa = 0.05 cx-1327 and the data are notfited the Genetic law of Independent Assortment (9P-Su:3p-susu: D)x5.327 and the data are not fittedthe Genetic law of independent Assortment (SP-Su-3p-susLE

51) Equation:

y = -4.63 + 1.38 * x

r = 0.9

coeffiecient of det = r^2 = 0.9^2

r^2 = 0.81
