What can you conclude if we fail to reject the null hypothesis for two individual variables, but reject the null hypothesis for the two joint variables?
11. If we reject the null hypothesis, what can we conclude, subject to the probability, α? Multiple Choice Reject the null with a probability, α, of making a Type I error. The alternative hypothesis is false. The null hypothesis is true. Both the null hypothesis and the alternative hypothesis are true. 12. The average cost of tuition and room and board at a small private liberal arts college is reported to be $8,500 per term. A financial administrator believes that...
You are doing a chi- square test for independence and find a significant result. What can conclude? A The null hypothesis is correct and there is no difference in the proportion of count in your single row. B . The null hypothesis is incorrect and there is probably a relationship between the two variables of interest. C.The null hypothesis is correct and there is no relationship between your two variables of interest. D.The null hypothesis is incorrect and there is...
Consider the following hypothesis test. p-value State your conclusion. Do not reject Ho, we cannot conclude that σ12-022 Do not reject Ho, we can conclude that σ12 ng2 test statistic s
We have been through the process of arrest, trial, and sentencing. Does this change your opinion of the judicial process?
If ?(?) = 0.6, ?(?) = 0.2, and ?(?|?) = 0.2, what can we conclude about the relationship between A and B? If ?(?) = 0.23,?(?|?) = 0.56, what can we conclude about the relationship between A and B? If ?(?) = 1 3 , and ?(? and ?) = 0, what, if anything, can we conclude about the relationship between C and D?
What can you conclude from these results? Is Betty’s hypothesis supported? Betty has the following hypothesis: Women are more likely to believe that hard work leads to success than men are. Betty ran a comparison of means test on survey data and had the following results from SPSS. The variable about "hard work" ranges from 1 to 10 with 1 being the strongest belief that hard work brings success and 10 being the strongest belief that hard work does NOT...
in a random sample of 452 people 326 voted yes on proposition W. Can we conclude that more than 70% of the population will vote this way? Compute the p-value.
Commute times in the U.S. are heavily skewed to the right. We select a random sample of 200 people from the 2000 U.S. Census who reported a non-zero commute time. In this sample the mean commute time is 27.5 minutes with a standard deviation of 18.9 minutes. Can we conclude from this data that the mean commute time in the U.S. is less than half an hour? Conduct a hypothesis test at the 5% level of significance. What is the...
1. (21.06) We can conclude from Examples 21.2 and 21.3 that mildly obese people spend less time standing and walking (on the average) than lean people Is there a significant difference between the mean times the two groups spend lying down? Use the four-step process to answer this question from the data in Table 21.1 TABLE 21.1 TIME (MINUTES PER DAY) SPENT IN THREE DIFFERENT POSTURES BY LEAN AND OBESE SUBJECTS GROUP Lean Lean Lean Lean Lean Lean Lean Lean...
