Answer 1

1)true

2)The hypothesis that your sample mean is significantly different from the population mean is called the Alternative hypothesis or  b) Research Hypothesis

3) If you are running a test to find out whether or not a particular drug works better than a placebo in controlling depression, and you have no idea whether the effects of the drug will increase depression or decrease depression, you want to run a  d) Two-Tailed Test

4)

When you incorrectly reject the null hypothesis and claim there are significant differences between your two means, and no such difference exists in the population, you have a a) Type I Error  

5)

A Type II Error occurs when you fail to reject the null hypothesis when it is true : False
