Question

Consider a hypothesis testing situation in which the null hypothesis is p = 0.48 and the alternative is p > 0.48. Data is gathered from a random sample, and calculations yield a value of z = 2.5. Which one of the following conclusions can be drawn based on this information?

The P-value is larger than 0.10.
There is a 2.5% chance that the null hypothesis is true.
The value of 0.48 is called a statistic.
The sample size must have been large.
None of the above answers are correct.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
