Media experts claim that daily print newspapers are declining because of Internet access. Listed below, from left to right and then top to bottom, are the numbers of daily print newspapers in a large region for a recent sequence of years. First find the median, then test for randomness of the numbers above and below the median using a = 0.05. What do the results suggest? 1602 1581 1567 1555 1542 1538 1523 1503 1495 1485 1480 1472 1455 1454 1455 1452 1431 1429 1406 1393 1377 The median is. (Type an integer or a decimal. Do not round.) Determine the null and alternative hypotheses. Ho: H₁: Determine the test statistic. (Type an integer or decimal rounded to two decimal places as needed.) Determine the P-value. (Round to three decimal places as needed.) Determine the conclusion to the test. What do the results suggest? There appears to be Ho. In terms of the hypotheses, there sufficient evidence to conclude that trend in the numbers of daily newspapers because

## Analysis of Decline in Daily Print Newspapers Media experts claim that daily print newspapers are declining because of Internet access. Listed below, from left to right and then top to bottom, are the numbers of daily print newspapers in a large region for a recent sequence of years. First, find the median, then test for randomness of the numbers above and below the median using α = 0.05. What do the results suggest? ### Data: Number of Daily Print Newspapers ``` 1602, 1581, 1567, 1555, 1542, 1538, 1523, 1503, 1495, 1485, 1480, 1472, 1455, 1454, 1455, 1452, 1431, 1429, 1406, 1393, 1377 ``` ### Steps to Analyze 1. **Determine the Median:** - The median is _______. (Type an integer or a decimal. Do not round.) 2. **Determine the Null and Alternative Hypotheses:** \( H_0 \): ____________________ \( H_1 \): ____________________ 3. **Determine the Test Statistic:** - _______ (Type an integer or decimal rounded to two decimal places as needed.) 4. **Determine the P-value:** - _______ (Round to three decimal places as needed.) 5. **Determine the Conclusion to the Test:** - ____ \( H_0 \). In terms of the hypotheses, there ________ sufficient evidence to conclude that _________________. 6. **Interpret the Results:** - There appears to be _______ trend in the numbers of daily newspapers because ____________________. ### Example: To guide you through with an example, here’s a sample way to approach filling out the sections: 1. **Median Calculation:** - After arranging the numbers in ascending order, find the central number. 2. **Hypotheses Identification:** - \( H_0 \): The numbers of daily print newspapers are random. - \( H_1 \): The numbers of daily print newspapers are not random. 3. **Test Statistic:** - You might use a statistical test like the Runs Test for Randomness to determine the statistic. 4. **P-value Calculation:** - Based on the test statistic, calculate
