The data for Proportion:
The question for the data: If your a teen do you own a smart phone?
The data for Mean: At what age will you pay off your student debts if you have any at all after you are done with school?

Sample Proprotion:
Hypothesis test results: Outcomes in : Scheer Proportion Success : Yes p : Proportion of successes H_{0} : p = 0.75 H_{A} : p ≠ 0.75

90%, 95%, 99% confidence interval for population proportion:
99% confidence interval results: p : Proportion of successes Method: StandardWald

95% confidence interval results: p : Proportion of successes Method: StandardWald

90% confidence interval results: p : Proportion of successes Method: StandardWald

The hypothesis for the data:
H_{ο}: p=.75
H_{1}: p≠.75
sampling distribution of the sample proportion is:
 Shape: bell shaped
 Mean: 0.96551724
 Standard deviation: 0.08040844
Conduction a Hypothesis test at the α=.05 level of significance, the results are:
Hypothesis test results: Outcomes in : Scheer Proportion Success : Yes p : Proportion of successes H_{0} : p = 0.75 H_{A} : p ≠ 0.75

Since the PValue is less than α=.05, we reject teh H_{ο} because it is less. If you change the α=.01, then the conclusionis our hypothesis would not change. We should still reject H_{ο}, because teh PValue is still less than α=.01

Hypothesis test for the data:
H_{ο}: μ=41
H_{1}: µ=41
sampling distrubiton of the sample mean is:
Shape: bell shaped
Mean: 22.245455
Standard Deviation: 15.590083
Conducting a hypothesis test at the α=.05 level of significance, the results are:
Hypothesis test results: μ : Mean of variable H_{0} : μ = 41 H_{A} : μ > 41

since the PValue is greater than α=.05, we reject teh H_{ο }becasue it is greater. If you change the α=.01, the the conclusion of the hypothesis would not change. We would not rejecct the PValue is greater than α=.01
