1. H = 80.329 0= 2.377 n= 776 Given the values above, according to the Central Limit Theorem, what would be the mean of the distribution of sample means? Round to 3 decimal places. 2. Research question: Is the average ACT score in the population of all students who complete a test prep program greater than the known national average of 18? Ho: H =18 Ha: M >18 Data were collected from a large sample of 100 students who have completed the test prep program. The mean ACT score in that samples was 20. The standard error was 0.6. Compute the test statistic using the following formula: teststatistic=samplestatistic-nullparameterstandarderrorteststatistic=samplestatistic-nullpara meterstandarderror Round your final answer to four decimal places. 3. Data concerning age (in years) were collected from a sample of 548 online STAT 200 students during a summer semester. We want to know if the average age in this population is different from 25 years: Ho: M =25 Ha: H #25 Summary Statistics Variable N Mean StDev SE Mean Age 548 24.68 7.571 0.323 Use the information in the descriptive statistics table above to compute the t test statistic. Round your final answer to three decimal places. 4. U= 5 0= 6.6 n= 37 Compute the standard error of the mean
