Solution
Sure, here are the answers to your questions:
-
A pregnancy test reporting that a woman is not pregnant even though she is, is an example of a B. Type II error. This is because a Type II error is when we fail to reject a false null hypothesis, also known as a false negative.
-
We say that an outcome is statistically significant if ‘p’ is B. less than 0.05. This is because a p-value less than 0.05 is generally considered statistically significant in most scientific studies.
-
The following represents a null hypothesis: A. There is no relationship between the hours of sleep and test performance. A null hypothesis typically proposes that no significant difference or relationship exists.
-
The following accurately represents a one-tailed alternative hypothesis: G. The younger group will spend more time on their cell phones than the older group. A one-tailed hypothesis predicts a direction of the relationship between variables.
-
The following accurately represents a two-tailed alternative hypothesis: J. There will be a difference between the number of aggressive actions performed by male and those performed by females. A two-tailed hypothesis does not predict a direction of the relationship, it only predicts that a relationship exists.

A 2011 survey by the Bureau of Labor Statistics reported that 91% of Americans have paid leave. In January 2012, a random survey of 1,000 workers showed that 89% had paid leave.The resulting p-value is 0.0271; thus, the null hypothesis is rejected. It is concluded that there has been a decrease in the proportion of people who have paid leave from 2011 to January 2012.What type of error is possible in this situation? Type I Type II Neither Both
