2. The following are data for thickness (in cm) of tree bark, obtained from a SRS. Let's assume 1.3 cm for the population. that σ 3.0 3.2 1.7 0.3 2.4 2.6 2.7 1.5 2.0 3.1 0.2 2.2 3.6 3.2 4.0 1.3 3.2 2.3 2.7 1.4 1.6 (a) (4 points) Make a histogram of the data. Is there evidence against the conjecture that the data comes from a Normal distribution? (b) (4 points) Construct a 96% confidence interval for the mean...
A position-time graph is shown below: Position vs. Time 15 Position (cm) -> Time (seconds) -> Which statement accurately describes the motion of the object in the graph above over 10 seconds? The object moves forward at 1 cm/s, stops, and then continues at the same velocity. The object moves forward at 1 cm/s, stops, and then increases velocity to 2 cm/s. The object is at rest for 4 seconds and then moves forward for 4 seconds at 1 cm/s....

Which graph in diagram 1-36 below represents the motion of an object increasing in velocity? ER) CB) IC) Diegrem 1-36 10. A man walks at a speed of 3.00 m/s for 400 seconds, and then walks at 4.00 m/s for 300 seconds....
3. Sketch the velocity-versus time graph from the following position versus time graph: n) 0.5 1.5 2.5 3.5 t(S) -0.5
The data in the following table describe the initial and final positions of a moving car. The elapsed time for each of the three pairs of positions listed in the table is 0.46 s. Review the concept of average velocity in Section 2.2 and then determine the average velocity (magnitude and direction) for each of the three pairs. Note that the algebraic sign of your answers will convey the direction. Initial position x0 Final position x (a) +2.3 m +6.1...

The data in the following table describe the initial and final positions of a moving car. The elapsed time for each of the three pairs of positions listed in the table is 0.52 s. Review the concept of average velocity in Section 2.2 and then determine the average velocity (magnitude and direction) for each of the three pairs. Note that the algebraic sign of your answers will convey the direction.
