Answer:
This interval in the form of margin of error is expressed as 0.45 ± 0.15.
p = 0.45
MOE = 0.15
Step-by-step explanation:
A confidence interval is calculated from a sample statistic (in this case, a sample proportion) and substracted or added a margin of error (MOE) for the lower and upper bound respectively.
This can be expressed as:
If we substract the upper bound from the lower bound, we can calculate the margin of error as:
With this information, we can calculate the sample proportion p:
Then, we can express the confidence interval as:
