Homework Answers
1)
Stating that there was an effect when actually there is no effect
2)
Population parameters
3)
Reject the null hypothesis because the difference is not significant
4)
Larger sample size and smaller variance increases the likelihood of rejecting the null hypothesis
5)
CI = M +/- tcr * SE
CI = 55 +/- 2.064 * 2
CI = (55 - 4.128 , 55 + 4.128)
CI = (50.872 , 59.128)

To test the effectiveness of a treatment, a sample of n = 36 people is selected from a normal population with mean of μ = 60. After the treatment is administered to the individuals in the sample, the sample mean is found to be M = 55. (a) If the population standard deviation is σ = 13, can you conclude that the treatment has a significant effect? Use a two-tailed test with α = 0.05. (Round your answers to two...
