The data represent the time, in minutes, spent reading a
political blog in a day. Construct a frequency distribution using 5
classes. In the table, include the midpoints, relative
frequencies, and cumulative frequencies. Which class has the
greatest frequency and which has the least frequency?

A researcher records the amount of time (in minutes) that
parent-child pairs spent on social networking sites to test whether
they show any generational differences. From the following findings
reported in APA format, interpret these results.
Parents spent significantly less time on social networking sites
compared to their children
(MD = 42 minutes),
t(29) = 3.343,
p < 0.05,
d = 0.61.
State the research design used (repeated measures or matched
pairs).

The time, in minutes spent texting in class, is approximately
normally distributed with a mean of 6.2 minutes and a standard of
1.6 minutes.
The distance, in city blocks, that a student must travel to get
from one class to the next has a Chi-squared distribution with 4
degrees of freedom. (The standard city block is approximately 400
feet long)

The technology committee at a college has stated that the
average time spent by students per lab visit has increased, and
the increase supports the need for increased lab fees. To
substantiate this claim, the committee randomly samples 12 student
lab visits and notes the amount of time spent using the computer.
The times are given in the accompanying table.
Time Mins: 79, 62, 56, 55, 66, 69, 67, 68, 134, 55, 9, 62.

The technology committee of a small college has stated that the
average time spent by students per lab visit has changed recently.
To substantiate this claim, the committee randomly samples 12
student lab visits and notes the amount of time spent using the
computer, the times in minutes are as follows: 52, 57, 54, 76, 62,
52, 74, 53, 67, 73, 58, 62 If the previous average amount of time
spent using the lab was 55 minutes, at 95% confidence,...
