Answer:
1. 4 bags of 7 grapes
2. 27
Step-by-step explanation:
Answer: lower bound = 0.7404; upper bound = 0.8596
Step-by-step explanation:
The proportion p for this population:
p = ![\frac{240}{300}](https://tex.z-dn.net/?f=%5Cfrac%7B240%7D%7B300%7D)
p = 0.8
Confidence interval for proportion is calculated as:
p ± z-score.![\sqrt{\frac{p(1-p)}{n} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%20%7D)
Z-score for a 99% confidence interval is: z = 2.58
Calculating:
0.8 ± 2.58.![\sqrt{\frac{0.8(0.2)}{300} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B0.8%280.2%29%7D%7B300%7D%20%7D)
0.8 ± 2.58.![\sqrt{0.00053}](https://tex.z-dn.net/?f=%5Csqrt%7B0.00053%7D)
0.8 ± 2.58(0.0231)
0.8 ± 0.0596
This means that the lower limit of this interval is 0.7404 and upper bound is 0.8596
