Answer:
33.99
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 39.99 × 15/100
Discount = 39.99 x 0.15
You save = $6.00
Final Price = Original Price - Discount
Final Price = 39.99 - 5.9985
Final Price = $33.99
Answer:
From the sample of n= 200 people,
The proportion of people with kids is:
p'= 110/200= 0.55
The confidence interval for population proportion is given by:
![p' - Z_{\alpha /2} \sqrt[]{\frac{p'(1-p')}{n} } } \leq P\leq p' + Z_{\alpha /2}\sqrt[]{\frac{p'(1-p')}{n} } }](https://tex.z-dn.net/?f=p%27%20-%20Z_%7B%5Calpha%20%2F2%7D%20%5Csqrt%5B%5D%7B%5Cfrac%7Bp%27%281-p%27%29%7D%7Bn%7D%20%7D%20%20%20%7D%20%5Cleq%20P%5Cleq%20p%27%20%20%2B%20Z_%7B%5Calpha%20%2F2%7D%5Csqrt%5B%5D%7B%5Cfrac%7Bp%27%281-p%27%29%7D%7Bn%7D%20%7D%20%20%20%7D)
![= p' - Z_{\alpha /2} \sqrt[]{\frac{0.55(0.45)}{200} } } \leq P \le p' + Z_{\alpha /2} \sqrt[]{\frac{0.55(0.45)}{200} } }](https://tex.z-dn.net/?f=%3D%20p%27%20-%20Z_%7B%5Calpha%20%2F2%7D%20%5Csqrt%5B%5D%7B%5Cfrac%7B0.55%280.45%29%7D%7B200%7D%20%7D%20%20%20%7D%20%5Cleq%20P%20%5Cle%20p%27%20%2B%20Z_%7B%5Calpha%20%2F2%7D%20%5Csqrt%5B%5D%7B%5Cfrac%7B0.55%280.45%29%7D%7B200%7D%20%7D%20%20%20%7D)

Where P is the population proportion and Z is the critical value at a given level of significance α.
