The table above outlines the shoe sizes of 15 randomly chosen high school female students.

Answer the questions below:

1. Find the mean of this data. Round to the nearest tenth. (2 pts)

2. Find the standard deviation of this data. Round to the nearest whole number. (2 pts)
3. Use the mean and standard deviation found in numbers 1-2 to create a normal distribution curve using the graph below. You must label the following:
a. mean shoe size
b. shoe sizes that are 1, 2, and 3 standard deviations from the mean
c. the percentages in each piece of the normal distribution curve
d. title of the data
4. What percentage of females have shoe sizes from 5.8-8.8? (2 pts)

5. What percentage of females have a shoe size smaller than 4.8? (2 pts)

6. What percentage of females have a shoe size bigger than 9.8 or smaller than 5.8? (2 pts)

7. Are there any outliers in the data set? Yes or No?(2 pts)

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
