Q2: The following data represent the weight loss in pounds of individuals on a five-week weight control program (n=25). Answer the following briefly. 9, 11, 6, 12, 10, 5, 11, 4, 11, 11, 2, 10, 8, 7, 5, 1, 8, 10, 11, 4, 3, 9, 9, 12, 11. 1- Deduce the number of class interval and the interval width? 2- Set up the frequency table, the relative frequency table, and the cumulative frequency table for the above data? 3- Draw the histogram. Be sure to label the axes. Is the distribution of data skewed or Symmetry? 4- Calculate i, Median 11. Mode ? 5- What is the probability that a person selected at random would have a weight loss equal or less than 7 pounds ?
Find the z-score that cuts off 35% in the tail on the right. (Hint: if you can’t find that EXACT percentage on the table, then there should be two VERY CLOSE numbers, one just under the percentage you’re looking for, and one just over it. Either one of those two is fine—so just pick the one that appears in the answer options below). Group of answer choices
see the photo for details A civil engineering student has delivered a cylinder of concrete for the "concrete strength competition" held between universities. The strength of the student's concrete cylinder is normally dispersed with N(4X0, 9X) kN (write the last number of your student number instead of X). For example, if the last number of your student number is 4, the normal distribution will be N(440.94). The student will compete in the last place in the competition and until that point the two highest strengths in the competition are 500 kN and 350 kN. What are the odds of the student coming second in the competition? The student's cylinder is being tested and under a load of 450 kN the cylinder has shown no signs of breaking. What are the chances of the student winning first place?

The national distribution of fatal work injuries in a country is shown in the table to the right under National %. You believe that the distribution of fatal work injuries is different in the western part of the country and randomly select 6231 fatal work injuries occuring in that region. At a = 0.05 can you conclude that the distribution of fatal work injuries in the west is different from the national distribution? Complete parts a through d below. Equipment Cause National % 44% Western Frequency Transportation 2895 18% 1160 Assaults Falls Harmful fumes 14% 803 13% 754 9% 532 Fires 2% 87 O B. The distribution of fatal work injuries in the west is the same as the expected distribution. O C. The distribution of fatal work injuries in the west is 44% transportation, 18% equipment, 14% assaults, 13% falls, 9% harmful fumes, and 2% fires. Which hypothesis is the claim? O Ho V H. b.
