Answer with explanation:</h2>
Consider a sampling distribution with p equals 0.12 and samples of size n each.
Then, formula for mean = p
Formula for standard deviation= 
(a) For a random sample of size n equals 5000.
Mean = 0.12
Standard deviation= 
(b) For a random sample of size n equals 1000.
Mean = 0.12
Standard deviation= 
(c) For a random sample of size n equals 500.
Mean = 0.12
Standard deviation= 
Answer:
a. Mean = 155.1 grams
b. Standard deviation = 0.37
c. Fractional uncertainty = 0.074
Step-by-step explanation:
a. Average weight
This is same as the mean weight;
Mathematically, that would be; sum of the weights/ the number of weights
= (155.1 + 154.8 + 155.5 + 155.3 + 154.6)/5 = 775.3/5 = 155.06 which is approximately 155.1
b. Standard deviation
Mathematically; we calculate that using the formula;
√{(x-mean)^2/(N-1)}

c. Fractional uncertainty
= Standard deviation/number of measurements = 0.37/5 = 0.074
She has no more white ribbon because she exchanged it for yellow.
Answer: B
Because they’re congruent angles
