The test grades for a certain class were entered into a Data Analysis worksheet, and then the following descriptive statistics were obtained. Grades : N = 32, Mean = 78.1, Median = 77.0, StDev = 10.61, Min = 38.0, Max = 96.0, Q1 = 69.0 and Q3 = 85.0 You happen to see on a piece of scrap paper that the lowest grades were 38, 58, 60, 60... but you don't know what the other individual grades are. Nevertheless, a knowledgeable user of statistics can tell a lot about the data set simply by studying the set of descriptive statistics above. Describe the shape and the spread of the distribution

f

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
