Question

Answer, please please

Answer 1

a) 2, 4, 6, 7, 7, 9, 14

Mean (average): $\frac{2+4+6+7+7+9+14}{7}$ = $\frac{49}{7}$ = 7

Median (middle number) : 2, 4, 6,        7,         7, 9, 14  = 7

Mode (most common number): 2, 4, 6,  7, 7,  9, 14 = 7

Midrange (average of smallest & greatest term): $\frac{2+14}{2}$ = 8

b) 2, 4, 6, 7, 7, 10, 14

Mean (average): $\frac{2+4+6+7+7+10+14}{7}$ = $\frac{50}{7}$ = 7.1

Median (middle number) : 2, 4, 6,        7,         7, 10, 14  = 7

Mode (most common number): 2, 4, 6,  7, 7,  10, 14 = 7

Midrange (average of smallest & greatest term): $\frac{2+14}{2}$ = 8

c) the only thing different between part (a) and part (b) is the MEAN

d) 2, 4, 6, 7, 7, 9, 10

Mean (average): $\frac{2+4+6+7+7+9+10}{7}$ = $\frac{45}{7}$ = 6.4

Median (middle number) : 2, 4, 6,        7,         7, 9, 10  = 7

Mode (most common number): 2, 4, 6,  7, 7,  9, 10 = 7

Midrange (average of smallest & greatest term): $\frac{2+10}{2}$ = 6

The differences between part (a) and part (d) are the MEAN and MIDRANGE
