Answer:
a) (0.576, 0.624)
Step-by-step explanation:
Given that the sample proportion (p) = 60% = 0.6, sample size (n) = 900, confidence (C) = 85%
α = 1 - C = 1 - 0.85 = 0.15
α/2 = 0.075
The z score of α/2 (0.075) corresponds with the z score of 0.425 (0.5 - 0.075) which is equals to 1.44, hence 
The margin of error (E) is:
The confidence interval = p ± E = 0.6 ± 0.024 = (0.576, 0.624)
Answer:
1/56
Total letters are 8
probability of first selecting c is 1/8 and since it's not replaced, probability of selecting e is 1/7
Total probability= 1/8*1/7=1/56
Therefore, total probability is 1/56
