Question
In 2011, researchers at St. Lawrence University had students participate in a series of experiments whose goal was to determine if gum chewing affected cognitive ability. One task given students was to write down names of as many animals as possible in 90 seconds (variable Animal Naming). There were 40 students who performed this task after chewing gum that they discarded just prior to the task. Use the output below to answer the questions for the gum chewing students. Write out the word TRUE or FALSE for your answers. (a). [2] True/False: There were about 8 female students who were able to name 25 animals. (b). [2] True-False: There were more male students than female students. (c). [2] True/False: The median number of animals named appears to be about the same for females and males. (d). [2] True-False: The range for males appears to be larger than for females. (c). [2] About how many females could name 30 or more animals?Explanation / Answer
(a) True,
We are given number of animals named of horizontal axis and number of males/females on vertical axis. Thus if we see at the intersection of the two axis, we can observe that around 8 females were able to name 25 animals.
(b) False.
The values on vertical axis male has smaller values than the on vertcal axis for female.
Thus the there are more females than males.
(c) False
The median is the mid value of observation and here we can see though both male and female may have around same lower values on vertical axis but clearly, female students have higher upper values around 8 though it is around 3 for males. Thus median will not be the same.
(d) False
Clearly. it can be observe the range of values of female is much wider than male.
(e) Around 5 females could name 30 or more females
