equal to, 400 and 440
Notice, we can totally avoid the calculations here.
We can answer first blank by just looking at the curve from January to May. This curve is linearly increasing till May. So answer must be Equal To.
Now 2nd blank, out of 8 data points, 5 have less than 420 value. So average must be around 420, unless other 3 data points are way too high, which is not the case here. So answer must be between 400 and 440.
But still i have performed calculations down below.
1. The percent change in the number of customers who switched services from March to May is approximately _____ the percent change in the number of customers who switched services from January to March.
percentage of customers who switched services from March to May = (65/352)100 = 18.46%
percentage of customers who switched services from January to March = (52/300)100 = 17.3%
roughly they are equal.
2. From January to August, the average (arithmetic mean) number of customers who switched falls approximately between______
avg = (300 + 321 + 352 + 381 + 417 + 463 + 522 + 580) / 8 = 417
Between 400 and 440.

i) percent change in the number of customers who switched services from March to Ma= 52/300*100=17.xx
percent change in the number of customers who switched services from January to March= 65/352*100= 18.xx
Thus 17.xx/18.xx= close to 1 hence almost equal
ii) Average = 300+321+352+381+463+417+522+580/ 8= 416
Thus its between 400 and 440
