poll surveyed people about taxing sugar-sweetened beverages. The results are presented in the table below, and are classified by ethnic group and response type. Are the poll responses independent the participants' ethnic group? Conduct a test of independence at the 5% significance level. Opinion/ Ethnicity Asian- American White/Non- Hispanic African- American Row Total Latino Against tax 48 432 41 160 681 In favor of tax No opinion 55 235 23 147 460 16 42 17 18 93 Column Total 119 709 81 325 1234 O Part (a) O Part (b) O Part (c) Part (d) O Part (e) What is the test statistic? (Round your answer to two decimal places.) O Part (f) What is the p-value? O p-value < 0.001 0.001 < p-value < 0.010 0.010 < p-value < 0.025 O 0.025 < p-value < 0.050 0.050 < p-value < 0.100 O p-value > 0.100 Explain what the p-value means for this problem. O If Ho is true, then there is a chance equal to the p-value that the value of the test statistic will be equal to or less than the calculated value. O If Ho is true, then there is a chance equal to the p-value that the value of the test statistic will be equal to or greater than the calculated value. O If Ho is false, then there is a chance equal to the p-value that the value of the test statistic will be equal to or less than the calculated value. O If Ho is false, then there is a chance equal to the p-value that the value of the test statistic will be equal to or greater than the calculated value.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
