Before the study, it was known the average time to quit was 2.3 months with a standard deviation of 1.1. Using a sample of 50 adults on the new treatment, the sample average time was 1.9 months. Questions: 6) what is the test value for the sample of 50 adults? Question 7: The p-value for the test value should be? Question 8: which of the following statements about the significance this study at a 0.05 level is correct?: A) The p-valueof test value is greater than .05, it is significant. B) The p-value of the test value is greater than, 0.05, it is not significant. C) The p-value of the test value is less than .05 it is significant.
