HELP PLEASE !!!
A store owner asks each person to write "Yes" or "No" on a slip of paper as they leave, secretly writing down whether they were happy with their experience. At the end of the day, the owner selects 12 slips at random and looks at them.
These were the results: yes, yes, yes, no, yes, no, yes, yes, no, yes, no, yes

Estimate the proportion of all shoppers who were happy with their experience that day.

On a different day, the owner found that 25% of the 12 selected slips were marked "Yes." Should the store owner believe that these two results reasonably represent the overall proportion of happy shoppers, or should the owner gather more data? Explain how you know.

The owner should gather more data.

"A proportion is an equation in which two ratios are set equal to each other."

Consider given situation,

The results on the first day: { yes, yes, yes, no, yes, no, yes, yes, no, yes, no, yes}

Total slips = 12

number of slips marked yes: n(Yes)

On day 1, n(Yes) = 8

So, the proportion of happy shoppers would be,

= 8/12

= 67.7%

This means, approximately 68% of the 12 selected slips were marked "Yes"

On a different day, the owner found that 25% of the 12 selected slips were marked "Yes"

This means the percentage of happy shoppers decreased.

From these two results we cannot determine where people are happy shoppers or not.

So, the owner should gather more data.
