Crash Commercial airplanes have an excellent safetyrecord. Nevertheless, there are crashes occasionally, withthe loss of many lives. In the weeks following a crash,airlines often report a drop in the number of passengers,probably because people are afraid to risk flying.a) A travel agent suggests that since the law of averagesmakes it highly unlikely to have two plane crasheswithin a few weeks of each other, flying soon after acrash is the safest time. What do you think?b) If the airline industry proudly announces that it hasset a new record for the longest period of safe flights,would you be reluctant to fly? Are the airlines due tohave a crash?

The ratio of the lengths of the second and the fourth fingers, denoted 2D:4D, is an indicator of the level of prenatal testosterone. It is known that higher prenatal testosterone levels are associated with a lower 2D:4D value. Since testosterone levels are known to be related to behavioural traits, it has been conjectured that certain types of aggressive and dominant behaviours may be associated with lower 2D:4D values. van der Meij et al. (2012) conducted a study that investigated the possible relationship between 2D:4D and so-called "sociable" and "aggressive" dominance. For the study, 84 male students completed two questionnaires, measuring sociable and aggressive dominance respectively, on which high scores related to increased aggression. After some adjustments, a score between 1 and 6 was recorded for each subject on each questionnaire. The participants' hands were scanned and measurements taken, on which a 2D:4D measure could be recorded per subject by averaging the ratio for…
In the vertical-horizontal line illusion, the two lines are exactly the same length, but the vertical line appears to be much longer. To examine the strength of this illusion, a researcher prepared an example in which both lines were exactly 10 inches long. The example was shown to individual participants who were told that the horizontal line was 10 inches long and then were asked to estimate the length of the vertical line. For a sample of n = 25 participants, the average estimate was M = 12.2 inches with a standard deviation of s = 1.00. Calculate t statistic.
