The following random samples are measurements of the heat-producing capacity (in millions of calories per ton) of coal from two mines: Mine 1: 8380, 8180, 8500, 7840, 7990 Mine 2: 7660, 7510, 7910, 8070, 7790 Use the 0.05 level of significance to test whether the difference between the means of these two samples is significant. Instructions: Assume 8 = 0, in addressing the problem obtain the value of the test statistic and its corresponding p – value up to four decimal places.

1.56 Longleaf pine trees. The Wade Tract in Thomas County, Georgia, is an old-growth forest of longleaf pine trees (Pinus palustris) that has survived in a relatively undisturbed state since before the settlement of the area by Europeans. A study collected data on 584 of these trees. One of the variables measured was the diameter at breast height (DBH). This is the diameter of the tree at 4.5 feet, and the units are centimeters (cm). Only trees with DBH greater than 1.5 cm were sampled. Here are the diameters of a random sample of 40 of these trees: PINES 27 10.5 13.3 26.0 18.3 52.2 9.2 26.1 17.6 40.5 31.8 47.2 11.4 2.7 69.3 44.4 16.9 35.7 5.4 44.2 2.2 4.3 7.8 38.1 2.2 11.4 51.5 4.9 39.7 32.6 51.8 43.6 2.3 44.6 31.5 40.3 22.3 43.3 37.5 29.1 27.9 (a) Find the five-number summary for these data.

QUA For Numbers 11 to 15: To determine the efficacy and lethal dosage of cardiac relaxants, anesthetized guinea pigs are infused with a drug (A, B, C, or D) until death occurs. Each drug was randomly assigned to ten guinea pigs, and the total dosage required for death of each guinea pig was recorded (smaller lethal doses are considered more effective). The software output of the analysis are given below: ANOVA Assumption Checks ANOVA - total_dosage Homogeneity of Variances Test (Levene's) Sum of Squares Mean Square df1 df2 df 36 0.307 drug 265 88.49 9.87 <001 1.25 3 Residuals 323 36 8.97 Normality Test (Shapiro-Wilk) Statistic 0.979 0.670 11.

The "spring-like effect" in a golf club could be determined by measuring the coefficient of restitution (the ratio of the outbound velocity to the inbound velocity of a golf ball fired at the clubhead). Twelve randomly selected drivers produced by two clubmakers are tested and the coefficient of restitution measured. The data follow: Club 1: 0.8406, 0.8104, 0.8234, 0.8198, 0.8235, 0.8562, 0.8123, 0.7976, 0.8184, 0.8265, 0.7773, 0.7871 Club 2: 0.8305, 0.7905, 0.8352, 0.8380, 0.8145, 0.8465, 0.8244, 0.8014, 0.8309, 0.8405, 0.8256, 0.8476 Test the hypothesis that both brands of ball have equal mean overall distance. Use α = 0.05 and assume equal variances. Question: Reject H0 if t0 < ___ or if t0 > ___.
