On average, Americans have lived in 2 places by the time they are 18 years old. Is this average less for college students? The 67 randomly selected college students who answered the survey question had lived in an average of 1.99 places by the time they were 18 years old. The standard deviation for the survey group was 0.3. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Ho: P 2 Hị: 2 c. The test statistic t v = (please show your answer to 3 decimal places.) -0.273 d. The p-value = 0.3929 e. The p-value is >V a f. Based on this, we should fail to reject g. Thus, the final conclusion is that .. (Please show your answer to 4 decimal places.) ] the null hypothesis. The data suggest that the populaton mean is significantly less than 2 at a = 0.10, so there is statistically significant evidence to conclude that the population mean number of places that college students lived in by the time they were 18 years old is less than 2. O The data suggest that the sample mean is not significantly less than 2 at a = 0.10, so there is statistically insignificant evidence to conclude that the sample mean number of places that college students lived in by the time they were 18 years old is less than 1.99. O The data suggest that the population mean is not significantly less than 2 at a = 0.10, so there is statistically insignificant evidence to conclude that the population mean number of places that college students lived in by the time they were 18 years old is less than 2. h. Interpret the p-value in the context of the study. Olf the population mean number of places that college students lived in by the time they were 18 years old is 2 and if you survey another 67 college students, then there would be a 39.29120944% chance that the sample mean for these 67 college students would be less than 1.99.
