First, let's calculate the mean and the mean absolute deviation of the first bowler.
FIRST BOWLER: <span>8,5,5,6,8,7,4,7,6 Mean = (Sum of all data)/(Number of data points) = (8+5+5+6+8+7+4+7+6)/9 <em>Mean = 6.222</em> Mean absolute deviation or MAD = [</span>∑(|Data Point - Mean|]/Number of Data Points MAD = [|8 - 6.222| + |5 - 6.222| + |5 - 6.222| + |6 - 6.222| + |8 - 6.222| + |7 - 6.222| + |4 - 6.222| + |7 - 6.222| + |6 - 6.222|]/9 <em>MAD = 1.136</em>
SECOND BOWLER: <span>10,6,8,8,5,5,6,8,9 </span>Mean = (Sum of all data)/(Number of data points) = (<span>10+6+8+8+5+5+6+8+9</span>)/9 <em>Mean = 7.222</em> Mean absolute deviation or MAD = [∑(|Data Point - Mean|]/Number of Data Points MAD = [|10 - 7.222| + |6 - 7.222| + |8 - 7.222| + |8 - 7.222| + |5 - 7.222| + |5 - 7.222| + |6 - 7.222| + |8 - 7.222| + |9 - 7.222|]/9 <em>MAD = 1.531 </em> The mean absolute deviation represents the average distance of each data to the mean. Thus, the lesser the value of the MAD is, the more consistent is the data to the mean. <em>B</em><em>etween the two, the first bowler is more consistent.</em>
So, you start off with $3.50 you travle 6 miles every mile is 0.75 that means you would need to multiply 6 by 0.75.
6 0.75 it equals 4.5
So we have $4.50 we need to add $3.50 and in total $0.50 plus $0.50 would be a dollar + 3 dollars plus $4 would be 7 so 7 +1 is 8. and 8 is the answer.
