Construct a 95% confidence interval of the population proportion using the given information.

x = 45, n = 150

the lower bound is

the upper bound is

(round to three decimal places as needed.)

95% confidence interval of the population proportion is  (0.227, 0.373)

Step-by-step explanation:

Confidence Interval can be calculated using p±ME where

and margin of error (ME) around the mean can be found using the formula

ME= where

then ME= ≈ 0.073

Then 95% confidence interval would be 0.3±0.073 or (0.227, 0.373)

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
