A snowboard manufacturer has three plants, one in the eastern United States, one in the western United States, and one in Canada. Production records show that the U.S. plants each produced 10,000 snowboards last month, while the Canadian plant produced 8000 boards. Of all the boards manufactured in Canada last month, 4% had a defect that caused the boards to delaminate prematurely. Records kept at the U.S. plants show that 3% of the boards manufactured in the eastern United States and 6% of the boards manufactured in the western United States had this defect as well. a. What proportion of the boards manufactured last month were defective? b. What is the probability that a snowboard is defective and was manufactured in Canada? c. Given that a snowboard is defective, what is the probability that it was manufactured in the United States?

Use the following information.

The frequencies in a contingency table can easily be written as relative frequencies by dividing each frequency by the sample size. The contingency table below shows the number of U.S. adults (in millions) ages 25 and over by employment status and educational attainment.

	Educational Attainment
Status	Not a high school graduate	High school graduate	Some college, no degree	Associate's, bachelor's, or advanced degree
Employed	11.5	35.9	21.3	51.4
Unemployed	1.1	2.1	1.0	1.4
Not in the	15.4	22.7	9.4	15.4
labor force

Relative frequencies can also be calculated based on the row totals (by dividing each row entry by the row's total) or the column totals (by dividing each column entry by the column's total). These frequencies are conditional relative frequencies and can be used to determine if an association exists between two categories in a contingency table.

Calculate the conditional relative frequencies in the contingency table based on the row totals.

When we collect random samples to test the claim that the proportion of female CIA agents stationed in the United States is equal to the proportion of female CIA agents stationed outside the United States, there is a requirement that np $\geq$ 30 and nq $\geq$ 30.

Explain the nature of sound, and describe how it travels through the various parts of the ear.

The situation require inference about a mean. Identify as involving a single sample, paired data, or two independent sample. Justify your choice. An educational researcher wants to learn whether it is more effective to put questions before or after introducing a new concept in an elementary school mathematics text. He prepares two text segments that teach the concept, one motivating questions before and the other with review questions after. He uses each text segment to teach a separate group of children. The researcher compares the scores of the groups on a test on the material.

Use the table, which lists the distribution of educational achievement for people in the United States ages 25 and older. It also lists the results of a random survey for two additional age groups. Ages $$ \begin{matrix} \text{Educational attainment} & \text{25 and older} & \text{30-34} & \text{65-69}\\ \text{None-8th grade} & \text{4.7\\%} & \text{10} & \text{23}\\ \text{9th-11th grade} & \text{6.9\\%} & \text{23} & \text{26}\\ \text{High school graduate} & \text{29.5\\%} & \text{80} & \text{136}\\ \text{Some college, no degree} & \text{16.6\\%} & \text{56} & \text{77}\\ \text{Associate's degree} & \text{9.8\\%} & \text{34} & \text{41}\\ \text{Bachelor's degree} & \text{20.5\\%} & \text{75} & \text{78}\\ \text{Master's degree} & \text{8.7\\%} & \text{31} & \text{41}\\ \text{Professional/doctoral degree} & \text{3.3\\%} & \text{11} & \text{18}\\ \end{matrix} $$ Does the distribution for people in the United States ages 25 and older differ from the distribution for people in the United States ages 30-34?
