Homework Answers
A. There is a significant difference between the two variables.
Statistical significance is shown by the value p >0.05 . It means that the findings of the study can be generalized to the broader population. P refers to probability and 0.05 is 5%. This percentage has been used by statisticians as a benchmark. Since, in the given example, the value of p is .037, which is less than .05, there is statistical significance. There is significant difference between the variables.

Based on the P-value for his test and assuming a significance level of a = 0.05, what should Nathan conclude about the claimed distribution of baseball cards? Because P > a, there is insufficient evidence against the claimed distribution of baseball cards. Because P <a, there is insufficient evidence against the claimed distribution of baseball cards. Because P <a, there is significant evidence against the claimed distribution of baseball cards. Because P > a, there is significant evidence against the...

Answer option:
Since the P-Value is (greater. Less) than the
significance level (fail to reject. Reject) the
null hypothesis. There (is not. Is) sufficient
evidence to support the claim of a difference in measurements

Which of the following is a correct statement of the null hypothesis? Select one: a. There are no true differences between the groups. Any difference found is due to sampling error. b. There is a statistically significant difference between one group and another. c. The observed differences were created by bias. d. There is a positive direct correlation between one group and another.
