A group of teenagers want to know how fast, on average, they can type text messages.  The students each type the same text message and record their times. What type of study is ddscribed?

At a middle school campus, the number of text messages sent by males and females were analyzed. Twelve random female students and 12 random male students were asked how many text messages they sent that day. The following data was calculated from the number of text messages sent during the day for males and females.    Females   MalesMean 112 99Median 68 52Mode 78 78Range 84 76Based on these samples, what generalization can be made? A. Males sent more total text messages than females. B. A female sent the most number of text messages out of both groups. C. The modes of text messages sent by both males and females are the same. D. Not enough information is provided to draw any of these conclusions.Reset Next

A study was conducted to explore the possibility of a podcast treatment effect on someone's ability to estimate time. One version of the study involved 95 school students. Each student was led into a dark room, and asked to press a button exactly three minutes after a signal was given. The time that actually passed from the signal to the pushing of the button was recorded in seconds. The school students were allocated to a group randomly at the time that they signed up for the study. One group listened to a podcast during the study, while the other group did not. The researchers found a difference of 8.7 seconds between the mean of the times recorded for each group, with the group that listened to a podcast having the higher mean. The tail proportion from a randomisation test carried out with the data from the study was 109/1000. Is the observed difference unusual when compared to the 'just chance' distribution? (enter yes or no)

4) In a survey looking at the mobile phone usage habits of university students, the following question was asked.. "Thinking about the last day you attended campus, how many text messages did you send on that day? Choose from one of the following answers: 1. Zero text messages II. One to four text messages III. Four to eight text messages IV. More than eight text messages" The data from this survey should be regarded as including: A. Categorical variables measured on a nominal scale B. Quantitative variables measured on an interval scale C. A discrete variable measured on an ordinal scale D. Numerical variables measured on a ratio scale
