a professor is teaching three sections of the same course and wants to determmine if the proprtion of students who passed is statistically different across the classes. the report below shows how many students in each section passed and how many were enrolled

Section 1 - 82 passed 107 enrolled

Section 2 - 74 passed 108 enrolled

Section 3 - 89 passed 115 enrolled

conduct the chi-square test and report the final test statistic

2. Determine the area of the region between x = −1, x = 2, f(x) = 3x2, and the x-axis.

(a) 27

(b) 2 (c) 9 (d) 48 (e) 16

Complete parts​ (a) through​ (c) using the following data.

Row 1 1 2 2 2 2 2 6 6 6 8

Row 2 94 85 86 71 94 65 74 87 60 62

​(a) Find the equation of the regression line for the given​ data, letting Row 1 represent the​x-values and Row 2 the​ y-values. Sketch a scatter plot of the data and draw the regression line.

Input the values of the slope and intercept for the regression line when Row 1 represents the​ x-values.

.

y =_____ x+ ( __ , __ ) (Round to three decimal places as​ needed.)

​(b) Find the equation of the regression line for the given​ data, letting Row 2 represent the​ x-values and Row 1 the​ y-values. Sketch a scatter plot of the data and draw the regression line.

c) Construct a residual plot.

​(d) Determine if there are any patterns in the residual plot and explain what they suggest about the relationship between the variables. Choose the best answer in the parenthesis.

The residual plot (shows, or does not show ) a pattern because the residuals ( fluctuate or ,do not fluctuate)about 0. This implies the regression line ( is or is not)

a good representation of the relationship between the variables.

A shipping company handles containers in three different sizes: (1) 27 ft3 (3 Ý 3 Ý 3), (2) 125 ft3, and (3) 512 ft3. Let Xi (i = 1, 2, 3) denote the number of type i containers shipped during a given week. With

(a) Assuming that X₁, X₂, X₃ are independent, calculate the expected value and variance of the total volume shipped. [Hint: Volume = 27X₁ + 125X₂ + 512X₃.]

(b) Would your calculations necessarily be correct if the X_i's were not independent? Explain.

The expected value would not be correct, but the variance would be correct

. Neither the expected value nor the variance would be correct.    

The expected value would be correct, but the variance would not be correct.

Both the expected value and the variance would be correct.

The escape from the Malthusian trap, in which technological progress outstripped the effects of population growth, took place following the emergence of capitalism. Consider the three basic institutions of capitalism in turn:

2.   Explain how markets can provide both carrots and sticks to encourage innovation.

3.   How can production in firms, rather than families, contribute to the growth of living standards?

For its top​ managers, Airborn Travel formats its income statement as​ follows:

Airborn's relevant range is between sales of $256,000 and $362,000.

Requirement 1. Calculate the contribution margin ratio. Select the labels and enter the amounts to calculate the contribution margin ratio. ​(Enter the contribution margin ratio as a whole​ percentage, X%.)

Requirement 2. Prepare two contribution margin income​ statements: one at the $256,000 sales level and one at the $362,000 sales level. ​(Hint​: The proportion of each sales dollar that goes toward variable costs is constant within the relevant​ range.)First prepare the contribution margin income statement at the $256,000 sales level. ​(Use a minus sign or parentheses for a​ loss.)

Now prepare the contribution margin income statement at the $362,000 sales level. ​(Use a minus sign or parentheses for a​ loss.)
