On average, Americans have lived in 4 places by the time they are 18 years old. Is this average a different number for college students? The 41 randomly selected college students who answered the survey question had lived in an average of 4.16 places by the time they were 18 years old. The standard deviation for the survey group was 0.8. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Họ: pv 4 H: uv 4 c. The test statistic t v = 1.281 (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? v a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ...
