I added a picture so please check it
A)
<span>10, 15, 17, 19, 25 </span>
<span>Min: 10 </span>
<span>Median: 17 </span>
<span>Max: 25 </span>
<span>lower Quartile: (10+15)/2 = 12.5 </span>
<span>upper Quartile: (19+25)/2 = 22 </span>
<span>b) </span>

<span>c) </span>
<span>Mean: (10 + 15 + 17 + 19 + 25)/5 = 17.2 </span>
<span>[ ( 17.2 - 10 )^2 + ( 17.2 - 15 )^2 + ( 17.2 - 17 )^2 + ( 17.2 - 19 )^2 + ( 17.2 - 25 )^2 ] / 5 = 24.16 </span>
<span>√( 24.16 ) ≈ 4.92 </span>
<span>-------------- </span>

Angles on the same side are the same, so angle 1 is 110°.
Angle 1 and 2 are supplementary, so they add up to 180. Since we know angle 1 is 110, angle 2 must be 70°
