A car manufacturer wants to test whether consumer choice of body type (SUV, truck, or car) and color choice (black or white) are related. In a sample of 200 consumers, the following data is collected. Observed SUV Truck Car Black 24 36 53 White 15 31 41 If a Chi-Square Test of Independence were to be performed, one of the steps would be to calculate the expected values. Calculate the expected values, rounded to two decimal places. Expected SUV Truck Car Black [a] [b] [c] White [d] 29.14 [f]

Complete the following statements. True or False: Hypothesis tests are used to PROVE claims. [a] (true/false) Suppose you perform a hypothesis test that rejects the null hypothesis when the alpha level is 5%. Would the null hypothesis also be rejected if the alpha level was 10%? (Hint: Draw a picture.) [b] (yes/no/maybe) True or False: In a hypothesis test, your claim MUST be the alternative hypothesis. [c] (true/false) True or False:  In a right-tailed test, if the standardized test statistic is smaller than the critical value, then you would reject the null hypothesis. [d] (true/false) When setting up a hypothesis test, your goal is to support the claim. Then, you would want to make sure that the claim is the ??? hypothesis. [e] (null/alternative) The Chi-Square goodness-of-fit test and test of independence are always ??? – tailed. [f] (right/left/two) When beginning a hypothesis test, you start by assuming the ??? hypothesis is true. [g] (null/alternative) If the claim is the null hypothesis, then you either have enough evidence or don’t have enough evidence to ??? the claim. [h] (reject/support) The ??? hypothesis always contains the statement of equality. [i] (null/alternative)  

For the following scenario, determine the appropriate hypothesis test to use in order to test the claim. Then check to see if the conditions have been met. Support your answer for the conditions completely. z-Test for the Population Mean t-Test for the Population Mean z-Test for the Population Proportion Chi-Square Goodness-of-Fit Test Chi-Square Test of Independence Scenario 1: An article states that less than 8% of people accomplish their New Year’s resolution. In a sample of 45 individuals, you find that 6 have kept their New Year’s resolution.

For the following scenario, determine the appropriate hypothesis test to use in order to test the claim. Then check to see if the conditions have been met. Support your answer for the conditions completely. z-Test for the Population Mean t-Test for the Population Mean z-Test for the Population Proportion Chi-Square Goodness-of-Fit Test Chi-Square Test of Independence Scenario 3: You wish to test a researcher’s claim that the average time American’s spend watching television is 238 minutes per day. You collect a sample of 18 Americans and find the average time is 246 minutes with a standard deviation of 38 minutes. The distribution is likely right-skewed.

Unit Three Writing Assignment    In a 400–500-word essay; analyze the following image and connect it with World War II and the policy of Appeasement. A complete essay will have an intro, body, and conclusion and will specifically address the following:   A detailed explanation of Appeasement as it applies to World War II. Provide at least one example of this policy related to negotiations with Hitler at the Munich Conference. Evaluate the overall effect of this policy. (Was it good, bad, etc.… and explain your reasoning)      

This geologic structure is a(n) Image shows a fold.  The fold arches up.

Which of the following is the reservoir rock? The image shows layers of sedimentary rocks with the lower layers being cut by a fault and the upper layers folded up and over the faulted rocks (a monocline). Layer A is folded over the fault and has no oil in it. Layer B is folded over the fault and has oil seeping up through the layer and accumulating at the top of the fold. Layer C is faulted and has oil migrating up through the layer. Layer D is faulted and has oil migrating up through the layer.

The following is an example of a The image shows an up warped, arching fold with a layer of reservoir rock topped by a layer of seal rock.  Gas and oil have accumulated at the top of the fold in the reservoir rock and an oil well is pumping the oil. 

This geologic structure (pictured below) did which of the following in response to stress? Image shows rock layers that are folded into chevron folds (structural feature characterized by repeated well-behaved folded beds with straight limbs and sharp hinges.) 

The figure below shows the application of The image shows a hand smearing the top of a clay ball to the right while friction is holding the base of clay ball to the left.
