Answer:
The answer is below
Explanation:
The question is not complete, but I will solve a similar question. The question goes as:
A random sample of n measurements was selected from a population with unknown mean µ and known standard deviation σ. Calculate a 90% confidence interval for n = 49, ¯ x = 28, σ = 28
Solution:
A confidence interval is a range of numbers that contains a population parameter.
C = 90% = 0.9
α = 1 - C = 1 - 0.9 = 0.1
α/2 = 0.1/2 = 0.05
The z score of α/2 is the same as the z score 0.45 (0.5 - 0.05) which is equal to 1.65. Hence, the margin of error E is:
The confidence interval = 
The 90% confidence is between 21.4 and 34.6.
It’s D both a and b :)! Hope this helps
An important supporting detail can be seen in the sentence "The costs of illegal fishing are significant, with the value of pirate fish products estimated at between $10-$23.5 billion annually."
