Answer:
(0.767,0.833)
Step-by-step explanation:
The 95% confidence interval for population proportion p can be computed as
The z-value associated with 95% confidence level is 1.96.
whereas p=x/n
We are given that x=440 and n=550.
p=440/550=0.8
Thus, the required confidence interval is
0.767<P<0.833 (rounded to 3 decimal places)
Hence, we are 95% confident that our true population proportion will lie in the interval (0.767,0.833)
The result of the product of (0.36) and (0.53) is 0.1908
<h3>How to determine the product</h3>The product expression is given as:
(0.36) * (0.53)
Rewrite the product as follows:
Expand the product
Expand
Evaluate the sum
