In USE SALT Use the given information to construct a 90% confidence interval for the difference in mean quiz score for the two treatments (texting allowed and texting not allowed). (Use uno textino Htext SALT. Round your answers to three decimal places.) -20.101 x -11.439 Interpret the interval. The confidence interval allows us vV to conclude that the true mean quiz score for the no-texting treatment group is greater than the true mean quiz score for the texting treatment because zero is not contained in the confidence interval.

Question

A research article on the effect of multitasking on grade performance describes an experiment in which 62 undergraduate business students were randomly assigned to one of two experimental groups. Students in one group were asked to listen to a lecture but were told that they were permitted to use cell phones to send text messages during the lecture. Students in the second group listened to the same lecture but were not permitted to send text messages. Afterwards, students in both groups took a quiz on material covered in the lecture. Data from this experiment are summarized in the accompanying table.
