1. NHST techniques produce probability (p) figures such as p < .06. What event has a probability of .06 in NHST context? Explain.
2. Which of the following phrases go with events that are in the rejection region of a sampling distribution? Circle all that apply. It may be helpful to make a drawing.
p is small // retain the null hypothesis accept
H1 // middle section of the sampling distribution
3. The table below has blanks for you to fill in. Use the t-distribution table to find the t-critical values or in some cases, use these t-critical values to determine the other missing piece of information such as a level.
| N | A level | 2-tail or 1-tail test | critical value |
| 10 | .05 | two | |
| 20 | .01 | one | |
| 35 | .05 | 2.042 | |
| 6 | .001 | two | |
| 24 | one | 1.714 | |
| 56 | .02 | two |

1.) Is the national crime rate really going down? Some sociologists say yes! They say that the reason for the decline in crime rates in the 1980s and 1990s is demographics. It seems that the population is aging, and older people commit fewer crimes. According to the FBI and the Justice Department, 70% of all arrests are of males aged 15 to 34 years.† Suppose you are a sociologist in Rock Springs, Wyoming, and a random sample of police files...

Ste?1 (a) Find an interval containing the ponding P-value for a two-tailed test. we are given a Student's t distribution with df. # 9 and t-, 1.890. We wish to find an interval containing the corresponding P-value for a two-tailed test. To do this, we will use the Critical values for Student'st Distribution.

10. The owner of a company has asked you to conduct an evaluation of the customer satisfaction ratings to see if the company continues to provide customers with customer service that ranks above average. To be considered above average the average customer satisfaction score has to be above 7. Suppose a random sample of 60 customers is taken from a population to evaluate customer satisfaction. The sample mean is 7.25. The sample standard deviation is 1.05. The population mean is...

In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smalier. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.
