Applied Stats
State:
H0: p1-p2=0
Ha: p1-p2≠0
p1= proportion of students who recycle in group 1.
p2= proportion of students who recycle in group 2.
We will perform a 2 proportion z test at alpha level 0.05.
Plan:
Random: Took a random sample
Normal:
Independent: Met, 10(10)= 100, less than 10% of the population for both samples.
Do:
z= 1.29
pvalue= 0.20
p-hat1=0.5
p-hat2=0.3
p-hat=0.4
Conclude:
Since the p-value is bigger than alpha we reject H0 and cannot conclude Ha.
