Studdy Solution
STEP 1
Assumptions1. The sample size is836 adults.
. The percentage of adults who favor required gun registration is64%.
3. The margin of error is .
4. The confidence level is95%.
STEP 2
First, we need to calculate the lower and upper bounds of the confidence interval. The lower bound is the percentage of adults who favor required gun registration minus the margin of error, and the upper bound is the percentage of adults who favor required gun registration plus the margin of error.
STEP 3
Now, plug in the given values for the percentage of adults who favor required gun registration and the margin of error to calculate the lower and upper bounds.
STEP 4
Calculate the lower and upper bounds.
STEP 5
Now that we have the lower and upper bounds, we can write the statement about the percentage of adults in the country's population who favor required gun registration.
"There is95% confidence that between60.5% and67.5% of all adults in the country favor required gun registration."
