Step 1: Find the mean Step 2: Find the deviation from the mean Step 3: Take the absolute value of the deviation Step 4: Find the mean of the absolute deviation. x----x-mean 63 63-63 0 69 69-63 6 62 62-63 -1 57 57-63 -6 64 64-63 1 mean = (63+69+62+57+64)/5 = 63 Taking the absolute deviations, we have 0,6,1,6,1 Averaging these deviations : (0+6+1+6+1)/5 =14/5 = 2.8 Mean absolute deviation = 2.8

It is: 69

My block interchange says this. 55-57, 58-60, 61-64 (full size) 64-69, 70-79. That doesn't mean it won't fit. You would have to fab some motor mounts but physically it should drop in.

37: How? Every time a new number is put into the sequence, when you subtract it from the number before it, it will equal an odd number of greater value. For example; 72-69=3 69-64=5 64-57=7 57-48=9 48-37=11

The median of 2 numbers is the same as their mean, which is (69 + 78)/2 = 73.5

Between 60 and 70 the composite numbers are: 62, 63, 64, 65, 66, 68, 69. 60 and 70 are also composite.
