East Brunswick High school has 1200 students. A sample of 240 students was selected to study the average monthly income of students. Since sample size is greater than 30, how much error would you expect in finding the average income of all students? Group of answer choices 50% 20% 10% Can’t be determined. PreviousNext

Many people believe that the average number of Facebook friends is 338. The population standard deviation is 43.2. A random sample of 50 high school students in a particular county revealed that the average number of Facebook friends was 350. At α = 0.05, is there sufficient evidence to conclude that the mean number of friends is greater than 338? A survey of 15 large U.S. cities finds that the average commute time one way is 25.4 minutes. A chamber of commerce executive feels that the commute in his city is less and wants to publicize this. He randomly selects 25 commuters and finds the average is 22.1 minutes with a standard deviation of 5.3 minutes. At α = 0.10, is he correct? To test H0: σ = 1.2 versus H1: σ ≠ 1.2, a random sample of size n = 22 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to be s = 0.8, compute the test statistic. (b) If the researcher decides to test this hypothesis at the α = 0.10 level of significance, determine the critical values. (c) Will the researcher reject the null hypothesis? Why?

6. Many people believe that the average number of Facebook friends is 120. The population standard deviation is 36.8. A random sample of 37 high school students in a particular county revealed that the average number of Facebook friends was 147. At =α0.10, is there sufficient evidence to conclude that the mean number of friends is greater than 120? 1. State hypotheses by filling in the symbol (=,<,>, or not equal) and the population mean: 2. Critical z value is: 3. Z test value is: 4. Reject the null or do not reject the null: 5. Conclusion: is or is not enough evidence
