The data below represent the age (in years) for 30 randomly selected students on campus this quarter. 24 30 28 27 18 19 30 18 20 20 26 23 27 30 16 18 18 22 30 23 32 29 23 25 34 34 21 32 24 30 1. Use the data to fill in the frequency table below. Use 5 classes. Class Boundaries Frequencies Relative Frequencies 2. Use the information in the frequency table to draw a histogram representing the data. Please include units and labels on the axes. 3. Compute the 5 number summary for the data. Feel free to use your calculator (1 variable stats). 5. Compute the mean and standard deviation of the data. Feel free to use your calculator. By that I mean put it into a list and calculate 1 variable stats. 6. If you had to choose one combination of center/spread (choose from: mean/standard deviation, median/IQR, mode/range) to best summarize this set of data, which would you select? Please describe the rationale for your choice. Be sure you got your ideas for rationale from the text (not just an opinion).

At point A, a box having weight 5 lb is instantaneously moving around in a circle of radius $r_A = 2.2$ ft with a transverse speed of $v_{\theta A} = 3.7$ ft/s while connected to the end of a rope. The rope is wound inward (around the pole) at a constant speed of $v_r = 3.2$ ft/s. When the box reaches point B it is $r_B = 1.1$ ft from the pole. The magnitude of initial angular momentum of the box about the pole is $H_A =$ 3.52 slug$\cdot ft^2$ The magnitude of the final angular momentum is $H_B =$ slug$\cdot ft^2$ The final transverse velocity of the box is $(v_{\theta})_B = 7.4$ $\frac{ft}{s}$ The final radial velocity of the box is $(v_r)_B = 3.2$ $\frac{ft}{s}$ The final kinetic energy of the box is $T_B = 44.22$ $\times ft \cdot lb$ The work done in pulling the rope in from A to B is 1.936 $\times ft \cdot lb$

Text 1: A survey found that 92% of the men questioned preferred texting over talking on a phone and 81% of the women preferred texting over talking on a phone. There were 140 individuals in each sample. At α = 0.01, test the claim that there is no difference in the proportion of men and the proportion of women who favor texting over talking. Should we believe this claim? Given Hypotheses: H0 : p1 = p2 H1 : p1 ≠ p2 Look up and enter the correct critical value(s) from the chart.
