Question 104110: Numerous studies have shown that IQ scores have been increasing, generation by generation, for years (Flynn, 1984, 1999). The increase is called the Flynn Effect, and the data indicate that the increase appears to be about 7 points per decade. To demonstrate this phenomenon, a researcher obtains an IQ test that was written in 1980. At the time the test was prepared it was standardized to produce a population mean of μ = 100. The researcher administers the test to a random sample of n =16 of today’s high school students and obtains a sample mean IQ of M = 121 with SS = 6000. Is this result sufficient to conclude that today’s sample scored significantly higher tan would be expected from a population with μ = 100. Use a one tailed test with α = 0.1

You can put this solution on YOUR website!
If you will tell me the meaning of that SS number
I think I could give you some help with this and
the other problems you have posted.
