Textbook Question
Chapter 3, Problem 45PS
A study of 267 college students investigated the impact of smartphones on student connectedness and out-of-class involvement.
One finding showed that students reporting a higher perceived usefulness of smartphones in educational settings used their smartphone a higher number of times to send or read email for class purposes than students reporting a lower perceived usefulness of smartphones in educational settings.
a. Does the study suggest that perceived usefulness of smartphones in educational settings and use of smartphones for class purposes are positively
b. Do you think that there might be a cause-and-effect relationship between perceived usefulness of smartphones in educational settings and use of smartphones for class purposes? Explain.

this dataset is right below the HWA1 questions - it is
a Microsoft excel worksheet) and store it in your
favorite folder.
It contains 797 observations and 16 variables. The
"state" variable gives the names of the states
involved in this dataset.
• You need to have excel on your computer to open
this dataset.
i. You should use File > Import > Excel Spreadsheet
etc. as done in class 3 convert this file into a
Stata dataset. Once you are done, write the final
STATA code that makes the transformation of an
excel file to a STATA file possible.
ii. Write a code that will close the log file that has
been open since Question 1 part ii.
