1 answer:
Based on the data, the median time it takes players to complete the game is 1148 minutes.
<h3>What is the median?</h3>It is the mathematical value that is the middle when values are sorted.
<h3>How to find the median time?</h3>- Organize the values
457 - 548- 866 - 952 - 976 - 1037 - 1148 - 1235 - 1245- 1431-1486 - 1759 - 1864

Answer:
The probability that the proportion of books checked out in a sample of 412 books would differ from the population proportion by less than 4% is P=0.9255.
Step-by-step explanation:
The population's proportion is
If we take a sample of 412 books (n=412), we have a standard deviation of the sampling distribution of:
We have to calculate the probabilty that the sample proportion will be between 0.25 and 0.33.
