Answer:
The size of the sample needed = 67.65
Explanation:
Given that :
The margin of error = 10% = 0.10
The confidence level = 90% = 0.90
Level of significance = 1 - 0.90 = 0.10
At ∝ = 0.10
![Z_{\alpha/2}= Z_{0.10/2} = 1.645](https://tex.z-dn.net/?f=Z_%7B%5Calpha%2F2%7D%3D%20Z_%7B0.10%2F2%7D%20%3D%201.645)
Since the proportion of people that supported him/her is not given, we assumed p = 0.50
The margin of error formula can be expressed as:
![M.O.E = Z_{\alpha/2} \times \sqrt{\dfrac{p(1-p)}{n}}](https://tex.z-dn.net/?f=M.O.E%20%3D%20Z_%7B%5Calpha%2F2%7D%20%5Ctimes%20%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D)
![0.10 = 1.645 \times \sqrt{{\dfrac{0.5(1-0.5)}{n}](https://tex.z-dn.net/?f=0.10%20%3D%201.645%20%5Ctimes%20%5Csqrt%7B%7B%5Cdfrac%7B0.5%281-0.5%29%7D%7Bn%7D)
Squaring both sides; we have:
![0.10^2 = 1.645^2 \times {\dfrac{0.5(1-0.5)}{n}](https://tex.z-dn.net/?f=0.10%5E2%20%3D%201.645%5E2%20%5Ctimes%20%7B%5Cdfrac%7B0.5%281-0.5%29%7D%7Bn%7D)
![0.01 = 2.706025 \times \dfrac{0.25}{n}](https://tex.z-dn.net/?f=0.01%20%3D%202.706025%20%5Ctimes%20%5Cdfrac%7B0.25%7D%7Bn%7D)
![n= 2.706025 \times \dfrac{0.25}{0.01 }](https://tex.z-dn.net/?f=n%3D%202.706025%20%5Ctimes%20%5Cdfrac%7B0.25%7D%7B0.01%20%7D)
n = 67.65
Therefore, the required sample size = 67.65
Based on the information given, there's something wrong with the response of the friend towards the hospitality shown to him.
<h2>
What is hospitality?</h2>
From the question, it was stated that a friend came visiting and the friend's mum was hospitable to him and cooked for him. He wanted to pay for the food when he gets as he was going and this is wrong.
It's problematic that the friend is asking for payment for her loving presence. This illustrates that he hasn't been shown kindness or has probably been paying for things and doesn't have loving people around him.
In conclusion, it's awkward because one isn't meant to pay for a hospitable act.
