mean = 10. standard deviation = 1A bell-shaped distribution with the horizontal axis labeled from 0 to 20 by 2’s. The peak of the bell is centered at 10. The vertical axis labeled from 0 to 0.5 by 0.1’s. The bell curve is skinny, with most of the curve between 8 and 12.

A specific distribution in statistics whose graph is symmetric and bell-shaped, has an area of 1 between the \(x\)-axis and the graph, and has the \(x\)-axis as a horizontal asymptote.
Histogram from 16.5 to 25.5 by 0 point 5’s. Handspan, centimeters. Beginning at 16.5 up to but not including 17, height of bar at each interval is .001, .007, .013, .016, .052, .059, .087, .132, .159, .132, .104, .098, .069, .032, .023, .010, .004, .002, 0.
A histogram where the height of each bar is the fraction of the entire data set that falls into the corresponding interval (that is, it is the relative frequency with which the data values fall into that interval).
A sample is a subset of a population. For example, a population could be all the students at one school in grade 11. One sample of that population is all the grade 11 students who are taking Spanish.
From an earlier course.
A sampling distribution is a distribution of statistics obtained from samples drawn from a specific population. For example, a group of students draw several samples from a population that has 70% of items that Pass. The proportion of papers from each sample that are marked Pass is shown in this dot plot.
