Question

A certain vehicle can travel 125 miles using 6 gallons of gasoline. How many gallons of gasoline are required to make a trip of 1500 miles? A S4 8 65 С.72 D. 83 E. 96 A group of 20 obese adult males was selected and randomly divided into two groups of 10 subjects each. In Group A, the experimental group, the men were involved in a vigorous, 20- -day exercise program and also given instructions on the importance of diet Members of Group B, the control group, received the diet instructions but were not involved in the exercise program. The reduction in their cholesterol levels was as follows Group A: 12, 10, 15, 11, 12, 8, 17, 11, 12, 12 Group B: 5, 3,7,2, 3, 5, 4, 5, 1, 61. Do you reject the null hypothesis? Yes, because the calculated t value is less than the table t value B. A. Yes, because the calculated t value is greater than the table t value C. No, because the calculated t value is equal than the table t value D. No, because the calculated t value is greater than the table t value 62. Is there a significant difference in the cholesterol levels between the two groups of subjects? A. No, there is no significant difference in the cholesterol levels between the two groups of subjects by looking or comparing the cholesterol levels of each group B. No, there is no significant difference in the cholesterol levels between the two groups of subjects by looking or comparing the means of each group C. Yes, there is significant difference in the cholesterol levels between the two gro ups of subjects by looking or comparing the calculated t value with the table t value D. There is no relationship between the two groups to determine significance 63. What type of research is this? A. A post facto research because the subjects were assigned to groups that they naturally belong B. A post facto research because the research is for making prediction C. An experimental research because it is for finding a cause D. It is both post facto and an experimental research 64. Identify both the IV, and DV A. Diet instructions, and exercise program B. Diet instructions, and cholesterol levels C. Diet instructions, exercise, and cholesterol levels D. Exercise program, cholesterol levels 65. If the t ratio was significant, calculate the effect size. A. 1 B. 5

Answer 1

60)

This is the problem where we have given that

125 km of travel 6 gallons.

From that we can calculate, 1km can travel in 6/125 gallon

Hence 1500km can travel in 1500*6/125=72 gallon

Hence correct answer is option C
