### Understanding Causes of Fatal Plane Crashes Over the Past 60 YearsAmong fatal plane crashes that occurred during the past 60 years, the following data has been recorded:- 438 crashes were due to pilot error- 95 crashes were due to other human error- 214 crashes were due to weather- 585 crashes were due to mechanical problems- 609 crashes were due to sabotage**Constructing the Relative Frequency Distribution**The relative frequency distribution helps us understand the proportion of each cause related to the total number of plane crashes. To find the relative frequency, use the formula:\[ \text{Relative Frequency} = \left( \frac{\text{Number of crashes for a specific cause}}{\text{Total number of crashes}} \right) \times 100 \]#### Completing the Relative Frequency Distribution TableTo complete the relative frequency distribution, the total number of crashes is needed:\[\text{Total number of crashes} = 438 + 95 + 214 + 585 + 609 = 1941\]Using the formula above, we can calculate the relative frequencies for each cause:1. **Pilot error**: \[ \frac{438}{1941} \times 100 \approx 22.6\% \] 2. **Other human error**: \[ \frac{95}{1941} \times 100 \approx 4.9\% \] 3. **Weather**: \[ \frac{214}{1941} \times 100 \approx 11.0\% \] 4. **Mechanical problems**: \[ \frac{585}{1941} \times 100 \approx 30.1\% \] 5. **Sabotage**: \[ \frac{609}{1941} \times 100 \approx 31.4\% \]### Relative Frequency Distribution Table | Cause | Relative Frequency (%) ||----------------------|------------------------|| Pilot error | 22.6 || Other human error | 4.9 || Weather | 11.0 || Mechanical problems| 30.1 || Sabotage | 31.4 |### Analyzing Aviation SafetyThe table indicates that sabotage and mechanical problems

A researcher would like to know whether there is a consistent, predictable relationship between ACT scores and GPA for high school students. A sample of 100 students is obtained from students who took the ACT in their Junior year. Based on the test results and gpa scores, students are classified as high or low for ACT and for GPA. The results are summarized in the following frequency distribution: ACT Score High Low High GPA 39 21 Low GPA 15 25 Based on the data, is there a significant relationship between ACT scores and GPA (α = .05). Compute the appropriate measure of association.

Suppose that a polling company surveyed 600 people about how much time they spend watching television each day. The results of this survey were compiled and used to create this relative frequency histogram. Assume that all percentages shown in the histogram are whole numbers. Each of the bars in this histogram includes only the left endpoint of the class except for the last bar, which also includes the right endpoint. What percentage of respondents said that they watch television at least six hours per day? How many respondents said that they watch television between three and five hours per day?
