Do college students enjoy playing sports more than watching sports? A researcher randomly selected ten Is the proportion of wildfires caused by humans in the south different from the proportion of wildfires college students and asked them to rate playing sports and watching sports on a scale from 1 to 10 with 1 caused by humans in the west? 419 of the 538 randomly selected wildfires looked at in the south were' meaning they have no interest and 10 meaning they absolutely love it. The results Of the study are shown caused by humans while 420 of the 582 randomly selected wildfires looked at the west were caused Pla n Vs. Watchin S rts Assume a Normal distribution. What can be concluded at the the a = 0.01 level of significance level of For this study, we should use Select an answer a. The null and alternative hypotheses would be: b. The test statistic (For intermediate statistics, please round to 1 decimal place. Then show your test statistic to 3 decimal places.) c. The p-value (If you do not have a Ti83/84, then please use the Google Sheet function d. The p-value is a e. Based on this, we should the null hypothesis. f. Thus, the final conclusion is that O The results are statistically significant at a = 0.01 , so there is sufficient evidence to concl that the population mean rating for playing sports is greater than the population mean rat: for watching sports. O The results are statistically significant at a 0.01, so there is sufficient evidence to concll that the ten students that were surveyed rated playing sports higher than watching sports average. C) The results are statistically insignificant at a = 0.01, so there is statistically significant evidence to conclude that the population mean rating for playing sports is equal to the population mean rating for watching sports. O The results are statistically insignificant at a = 0.01 , so there is insufficient evidence to cqnclude that the population mean rating for playing sports is greater than the population mean rating for watching sports. humans. What can be concluded at the Q 0.10 level of significance? a. For this Study, We should use Select an answer b. The null and alternative hypotheses would be: c. The test statistic (please show your answer to 2 decimal places.) d. The p-vlue = (Please show your answer to 4 decimal places.) 0.9861 e. The pvalue is f. Based on this, we should the null hypothesis. g. Thus, the final conclusion is that ... O The results are statistically insignificant at a = 0.10, so there is statistically significant evidence to conclude that the population proportion of wildfires caused by humans in the south is equal to the population proportion of wildfires caused by humans in the west. O The results are statistically significant at a 0.10, so there is sufficient evidence to conclude that the population proportion of wildfires caused by humans in the south is different from the population proportion of wildfires caused by humans in the west. O The results are statistically insignificant at a 0.10, so there is insufficient evidence to conclude that the population proportion of wildfires caused by humans in the south is different from the population proportion of wildfires caused by humans in the west. C) The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude that the proportion of the 538 wildfires that were caused by humans in the south is different from the proportion of the 582 wildfires that were caused by humans in the west. You are interested in finding a 95% confidence interval for the average number of days of class that college students miss each year. The data below show the number of missed days for 12 randomly selected college students. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a distribution. b. With 95% confidence the population mean number of days of class that college students miss days. and is between c. If many groups of 12 randomly selected non-residential college students are surveyed, then a percent of different confidence interval would be produced from each group. About these confidence intervals will contain the true population mean number of missed class days percent will not contain the true population mean number of missed class and about days. psychologist is interested in constructing a 95% confidence interval for the proportion of people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain. 66 of the 702 randomly selected people who were suryed agreed with this theoryl Round answers to 4 decimal places where possible. a. With confidence the proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain is betwee nd b. If many youps of 702 randomly selected people are surveyed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in rain and about percent will not contain the true population proportion. You measure 20 backpacks' weights, and find they have a mean weight of 74 ounces. Assume the population standard deviation is 3.3 ounces. Based on this, construct a 90% confidence interval for the true population mean backpack weight. Round your critical value to two decimal places. Give your answers as decimals, to two places. ounces
