Here is an example problem:
Here is an example problem:
In a small town in Massachusetts, a town well supplied water that was contaminated by industrial chemicals to the west side residents but not to the east side residents, because they used a different well.
Here is an example problem:
In a small town in Massachusetts, a town well supplied water that was contaminated by industrial chemicals to the west side residents but not to the east side residents, because they used a different well. During that period of time a sample of 414 births on the west side showed 16 birth defects and a sample of 228 births on the east side showed 3 birth defects.

Step 1 - [insert a description of a sample proportion]“Residents who were exposed to water contaminated with
industrial chemicals”
Step 1 - [insert a description of a sample proportion]“Residents who were exposed to water contaminated with
industrial chemicals”Step 2 – “had statistically significantly” [insert “different”, “higher”, “lower”,
“more”, “less” etc.] “had statistically significantly more”
Step 1 - [insert a description of a sample proportion]“Residents who were exposed to water contaminated with
industrial chemicals”Step 2 – “had statistically significantly” [insert “different”, “higher”, “lower”,
“more”, “less” etc.] “had statistically significantly more”
Step 3 - [insert the dependent variable]“birth defects”
Step 1 - [insert a description of a sample proportion]“Residents who were exposed to water contaminated with
industrial chemicals”Step 2 – “had statistically significantly” [insert “different”, “higher”, “lower”,
“more”, “less” etc.] “had statistically significantly more”
Step 3 - [insert the dependent variable]“birth defects”
Step 4 – [Insert the result in terms of a proportion or a percentage](.04)
Step 1 - [insert a description of a sample proportion]“Residents who were exposed to water contaminated with
industrial chemicals”Step 2 – “had statistically significantly” [insert “different”, “higher”, “lower”,
“more”, “less” etc.] “had statistically significantly more”
Step 3 - [insert the dependent variable]“birth defects”
Step 4 – [Insert the result in terms of a proportion or a percentage](.04)
Step 5 – “than” [insert a description of the other sample proportion],“than residents who were not exposed to the contaminated water”
Step 1 - [insert a description of a sample proportion]“Residents who were exposed to water contaminated with
industrial chemicals”Step 2 – “had statistically significantly” [insert “different”, “higher”, “lower”,

Step 4 – [Insert the result in terms of a proportion or a percentage](.04)
Step 5 – “than” [insert a description of the other sample proportion],“than residents who were not exposed to the contaminated water”
Step 6 – insert z statistic“z = 2.35”

Final Two-Sample Z-Test Report:
Residents who were exposed to water contaminated with industrial chemicals had statistically significantly more birth defects (.04) than residents who were not exposed to the contaminated water. z = 2.35, p = .001.
