consider a poll that reported that 41% of people from a certain region have tried marijuana. the survey polled 1,055 adults from the region and had a margin of error of plus or minus 3 percentage points with a 95% level of confidence. complete parts (a) through (c) below.\na. state the survey results in confidence interval form and interpret the interval.\nthe confidence interval of the survey results is ( , ).\n(round to two decimal places as needed.)
Answer
Explanation:
Step1: Identify the sample proportion and margin of error
The sample proportion $\hat{p}=0.41$ and the margin of error $E = 0.03$.
Step2: Calculate the lower - bound of the confidence interval
The lower - bound is $\hat{p}-E=0.41 - 0.03=0.38$.
Step3: Calculate the upper - bound of the confidence interval
The upper - bound is $\hat{p}+E=0.41 + 0.03=0.44$.
Answer:
$(0.38,0.44)$
