Which of the statements correctly describes the relationship between the mean and median in the histogram of the number of servings of fruit per day claimed by the 7474 seventeen‑year‑old girls? A) The mean and median are about equal because the distribution is right‑skewed. B) The mean is larger than the median because the distribution is right‑skewed. C) The median is larger than the mean because the distribution is right‑skewed. D) There is not enough information to tell us about the relationship between the mean and median in the histogram. (c) In general, you cannot find the exact values of median, quartiles, or mean from the histogram. What is special about the histogram of the number of servings of fruit that allows you to do this? Select an answer choice. A) We know exactly how many observations fall in each bin because of the way the bins are constructed. B) The sample size only consists of only 74 observations. Because the sample size is small, we can find the exact values. C) The distribution is right‑skewed. D) There is nothing special about the histogram, you can always find exact values for the median, quartiles, or mean.

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.

(b) You can also find the mean number of servings of fruit claimed per day from the histogram. First use the information
in the histogram to compute the sum of the 74 observations, and then use this to compute the mean. (Enter your answer
rounded to two decimal places.)
