What we Know: 3 box have some counters. There are 63 counters when they are all combined. A and B counters = 36 The difference between A and C is 10. Since we already know A and B we can subtract them from 63 to get C C= 63- 36 = 27 Now we have to find A by looking for what number gives us the difference of 10 when subtracted from C. 36 = 18+ 18 or 19+ 17 18 and 18 wont work because it does not give us the difference of 10. So A = 17 counters and B = 19 counters.
The parameter in this hypothesis test describes the entire population. So in this test, the parameter is looking into the summary number for instance like an average of all overweights who after undergoing this pattern/daily habits exhibits weight loss.
