In Lab 4 you also analyzed the cell phone use of students several years back At that time it was known that about 80 of all college students owned a cell phone In your analysis you found that a 95 confidence interval for the percentage of students in this university who owned a cell phone was 0 74 0 83 You also tested whether the data provide evidence that the proportion of students who own cell phones in this university is lower than the national figure You found the p value for that test was 0 24 Which of the following statements follow from this analysis Mark all that apply We are 95 confident that the proportion of students at this college who own a cell phone is between 0 74 and 0 83 Since 0 80 is in this interval we have inadequate evidence to conclude that the proportion of students at this university who own a cell phone is less than the national figure We are 95 confident that the proportion of students at this college who own a cell phone is between 0 74 and 0 83 Since 0 80 is in this interval we have enough evidence to conclude that the proportion of students at this university who own a cell phone is less than the national figure Since our p value is greater than our level of significance we conclude that our data is not adequate to conclude that the proportion of students at this college who own a cell phone is lower than the national figure Since 78 of the students sampled owned a cell phone we know that the percent of students at this school who own a cell phone is less than 80 the national figure
