First select "enter your own observations". under name of group 1 enter: in state students under name of group 2 enter: out of state students. under name of response variable enter: time. enter the below data under the heading "enter observations for each group, separated by spaces, or copy & paste from spreadsheet: " group 1: in state students: 2 4 1 2 2 2 4 7 4 1 2 2 1 group 2: out of state students: 1 2 2 3 9 1 12 5 2 2 5 1 make sure that the option "select test statistic: " says "difference of sample means". the test statistic appears at the bottom of the screen. what is the test statistic?

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
