Use the sample data and confidence level to construct the confidence interval estimate of the population proportion p. n equals 550 comma x equals 440 comma 95 % confidence nothingless thanpless than nothing (Round to three decimal places asneeded.)

(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)

central angle of a triangle has the same measure as its intercepted arc.
