- The critical z for a two tail test at alpha equals .05 is.
- Plus or minus 1.96
- Plus or minus 1.64
- Plus or minus 1.35
- Plus or minus 1.28
- It is known that the interval for p is (.025, .05). Your alpha is .07
- In this situation, always retain the null hypothesis
- In this situation, always reject the null hypothesis
- In this situation, sometimes retain the null hypothesis
- In this situation, sometimes reject the null hypothesis
- When we speak of p, we mean the following
- P is the probability that we reject the null hypothesis
- P is the probability that the null is true given we have rejected the null
- P is the probability that the null is true given we have retained the null
- None of the above
- Unlike the z, the t distribution has which properties
- We have to deal with degrees of freedom
- We do not know the population standard deviation
- Both A and B
- Neither A nor B
- The Chi-Square distribution….
- Is used to measure the difference in means
- Is used to measure the differences in standard deviations
- Both A and B
- Neither A nor B
- The Wonderlic test is a test of adult intelligence. It is known that the mean Wonderlic score is a 17 and it is known that the standard deviation is 6. Carla has a sample of 36 adults whose average score is a 14. This leads Carla to claim that the mean is less than the purported population mean. She tests at alpha=.07
