Answer:
Two sample test of means with unknown variance (standard deviation) but assumed equal
Step-by-step explanation:
For the scenario described above, we apply the two sample test means with unknown variance (standard deviation) but assumed equal test because, the there are two differebt or independent groups, each with its owm subjects or observations. The population variance or standard deviation aren't given. However, the variance are assumed to be equal., since the two groups of sample are chosen from the same population. Therefore, for the scenario described above, the most appropriate test would be a Two sample test of means with unknown variance (standard deviation) but assumed to be equal
It is 28 in squared :/ duh
Hello
77.49 - 3.99 = 12.25 * x
73.5 = 12.25x
(Divide both sides by 12.25)
6 = x
