7.) Using the bar graph in the image below, what was the enrollment rate (percent) of Black college students in 2000? How does the enrollment rate in 2000 compare to the enrollment rate in 2010? Figure 2. College enrollment rates of 18- to 24-year-olds, by race/ethnicity: 2000, 2010, and 2018 Percent 100 90 80 70 64 59 60 56 50 44 43 42 39 41 41 41 38 37 38 40 36 32 35 36 31 30 241 24 22 20 10 Total White Black Hispanic Asian Pacific Islander American Two or more Indian/Alaska Native races Race/ethnicity 2000 O 2010 2018 - Not available. ! Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 and 50 percent. NOTE: Data are based on sample surveys of the civilian noninstitutionalized population. Separate data for 18- to 24-year- olds who were Pacific Islander and of Two or more races were not available in 2000. In 2000, respondents of Two or more races were required to select a single race category. Prior to 2003, data for Asian 18- to 24-year-olds include Pacific Islander 18- to 24-year-olds. Race categories exclude persons of Hispanic ethnicity. Although rounded numbers are displayed, the figures are based on unrounded data.

Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
