can you please help me solve this two problem! thank you! 68. 21% , 95. 44% , 99.72% Larmi Rant 3) Use the Empirical Rule. The mean speed of a sample of vehicles slong a stretch of highway is 68 miles per hour, with a standard deviation of 5 miles per hour. Estimate the percent of vehicles when distribution.) speeds are between 53 miles per hour and 83 miles per hour. (Assume the data set has a bel-shaped X= 68+5=73 68- 5=63 73+5278 63. 5=58 78 +5= 83 58- 5253 99. 7% of vechicles travel between is mikes per hour and 83 miles per hour. 4) Find the five-number summary: and (b) draw a box-and-whisker plot of the data. 2 23 2 2 2 3 4 5 6 6 7 ; 7 7 8 8 8 7 9 9 9 9 9 3=1 92 419 4.5 2 2 7 m 421 1 3 2 93 8+9 1= 8.5 min = 2 1 6 81 = 4.5 18 24 14 9 92 = 7 185 7 82 = 8.5 max - 9
