Pasadena City College Hypothesis Test Statistics Calculations
Student Learning Outcomes
The student will use and derive fundamental concepts from the given information
The student will develop a stronger understanding of calculations behind hypothesis testing.
- The student will determine the unknown value by utilizing the acquired knowledge on hypothesis testing.
- Introduction
- Let’s assume a theoretical scenario. Let’s assume that we are asked to determine if a new plant treatment helps a certain species of plant to grow taller. We will only accept success if more than 50% of the treated plant grow taller. In this exercise it is irrelevant what the size of the plant is.
225 plants were treated in this example. The following results for a hypothesis test on proportion is given:
Ha: p>0.5p>0.5
H0: p=0.5p=0.5
We get that the p-value = 0.025
Question
Given that x = number of plants that grew taller, and in light of the above information find:
the number (x)(x) of plants that grew taller and
the success rate (p?)(p?) of plants that grew taller
Project Guidelines
Z-Test Statistic
p-value measures the area to the right of the test statistic. What is the z-value that has the given p-value?
Formula
Remember the calculation for the distance of the observed value to the null hypothesis.
z=p??pp?(1?p)n?z=p??pp?(1?p)n
