Then the price of hot dog buns would go up, I assume.
If you were the owner of the leading hot dog bun company, and hot dog prices went down, then more people would need to buy hot dog buns. So if you wanted to profit from that you'd raise your prices a little bit to make more money.

Answer: 271

Step-by-step explanation:

As per given description in the question, we have

Critical value for 90% confidence interval = $z_{\alpha/2}=1.645$

[using z-value calculator ]

Margin of error : E= 0.05

Since prior estimate of population proportion is unknown so we take p= 0.5

Formula we use to find the sample size :

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2$ [we assume p= 0.50]

i.e. $n=0.5(1-0.5)(\dfrac{1.645}{0.05})^2$

Simplify :

$\Rightarrow\ n=270.6025\approx271$

Therefore , the minimum sample size required = 271
