The customers gave Manufacture-R-US an average of 2. 4 for Manufacture-R-US’ on-site safety levels. There was a significant amount of standard deviation, with many customers giving safety level ratings between 1 and 4. The maximum safety level rating recorded was 10 and the minimum rating was 1 . Safety Rating (XX) Out of the 160 customers who were surveyed about the safety levels of Manufacture-R- US’ recognized by their industry regulator, half of the customers said Mann-Fact-R- US has high safety levels whereas the other half said that they have low safety levels.
Type of Industry (XII) 78 firms regarded themselves as part of the construction industry whereas the other 82 firms regard themselves as part of the mining industry. Question 2: Provide an interpretation of the analysis output for Safety Rating (XX) and Type of Industry (XSL O). Answer 2: The phi value was 2. 25 (greater than one) which indicating a positive relationship between safety rating and the type of industry. The p-value is 0. 011 which is less than the level of significance of 5%. The test statistic (Chi-square= 6. 4) is higher than he critical value. The results are unlikely to be due to chance alone and also a systematic association between the variables appears to exist. Question 3: Provide an interpretation of the analysis output for Safety Rating (XX) and Australian state (XSL 1). Answer 3: The phi value was calculated to be 0. 08 which is smaller than one, indicating a negative relationship between safety rating and the Australian State (Either Queensland or Western Australia). The p-value is 0. 08 which is higher than the level of significance of 5%.
Even though the phi value suggests that it’s a negative relationship, the p-value is more than 5%, therefore, even though it’s negatively Case Study: Type of Industry By littorals Therefore we can conclude that at 5% level of significance, the relationship between safety rating and the Australian State is not significantly negative. The chi-square value was 3. 41, which is lower than the critical value, which also suggests that a relationship between safety rating and the Australian State is not statistically significant.
