6. Fill in the missing values in the following table of relative frequency, labelled A- J. Show how you calculate each value, and put your final answer for each value in the table below (e.g., replace "A" with your found value). The method you use can be different from mine, but you must show how you arrive at each value. Hint: go in order. Find A, then B, etc. Tutorial video 3 should be very helpful here.

Determine if the data are approximately normally distributed. Please use R software.
A researcher is interested in the affects that a person’s avatar (i.e. visual representation of oneself) has on the number of profile views on Facebook.com. The average number of individual personal profile views is known to be 230 views per day (excluding bands, artists, etc.). The researcher creates 36 fictitious profiles that contain roughly the same information but the picture (avatar) is an animated .gif of a smiling face (36 faces randomly selected from a compilation of faces judged to be of average attractiveness). The results showed that of the 36 profiles the average number of views was 250 with a standard deviation of 60. Test the hypothesis that the average number of views for a smiling face gif is significantly different than the usual number of personal profile views.
A geographer studying West Africa would like to know the size of stones in the delta region where the Niger River runs into the Gulf of Guinea.
