Question: Can I please help interpreting the statistics I calculated. I want to understand how they connect to my hypothesis. My null hypothesis in words is:
Can I please help interpreting the statistics I calculated. I want to understand how they connect to my hypothesis.
My null hypothesis in words is:
There is no difference in the portion of people wearing a mask exiting the store in the morning compared to the evening.
The alternative hypothesis in words:
The proportion of people wearing a mask exiting the store in the morning is greater than the proportion of people wearing a mask in the evening.
Please include explanations for:
P value
Standard error
Confidence interval
Standard deviations
