1)INTRODUCTION: Colleges often report a combined tuition and fees figure. According to the College Board, the average cost of tuition for the 2017–2018 school year was $34,740 at private colleges, $9,970 for state residents at public colleges, and$25,620 for out-of-state residents attending public universities. Assume average yearly tuition cost of instate residents of 4-yr. public college is (mu) “μ” >/= is $12070 per year. (Null Hypothesis))

• Research online (by going to at least 15 college websites) to find costs of different public colleges to test this claim. (Hint: use Facts & Figures e,g Rutgers University,NJ)
• Use the T-test for a mean, since your sample is going to be less than 30 and an unknown population standard deviation.

Note: Make sure that your numbers only contain undergraduates and not graduates. As some of the websites were specific as to undergraduate or graduate and some probably contain both.

HYPOTHESIS: I think the average cost of tuition is lower than the assumed average stated.

Ho: μ (mu) >/= $12070.

H1: μ (mu) < $12070 (Claim)

DATA COLLECTION: Collect undergraduate students enrollment data from various college websites. Tabulate cost of tuition per year and the number of students enrolled. I already collected data for #1,an example and tubulated it as follows:

#	College	Tuition(In-state)	Number of Students
1	Rutgers University–New Brunswick	$11,999	49,577

• Find the lowest and the highest tuition. Calculate Range, Mean and Median for tuitions fees and enrollments.

HYPOTHESIS TESTING : (T-Test for the Population Mean, When σ Is Unknown(T-Test for a Mean)

Step 1: Identify the null and alternative hypotheses

Step 2: Set a value for the significance level, α = 0.05 is specified for this test

Step 3 : Determine the appropriate critical value

(Hint: Find the critical value at a=.025 and d.f. = 14, the critical value is –2.145.)– one tail

Step 4: Calculate the appropriate test statistic (i.e t-test statistic-“t alpha” )

Step 5:Compare the t-test statistic with the critical t-score.Compute the sample test value.

Step 6: Make the decision to reject or not reject the null hypothesis.

Step 7: Summarize the results. (conclusion)

2)Chi-Squared Independence Test

• Step 1: State the hypotheses and identify the claim. E.g. I claim that there is a correlation between the number of students at a college and the cost of tuition per year. Here is the data that is collected: (just an example to show the table – can change figuresif needed) Suppose α = 0.05 is chosen for this test

Cost of Tuition			Number of Students
	1000-9999	10000 -19999	20000 -29999	30000 – 39999	40000 – 49999	Total
$3000 – $6000
$6001 -$9000
$9001 – $12000
$12001 – $15000					1
$15001 -$18000
Total

Ho: The cost of tuition is independent of the number of students that attend the college. (x²=0)

H1: The cost of tuition is dependent on the number of students that attend the college. (claim : x²>0)

Step 2: Find the critical value

Step 3: Compute the test value. First find the expected value:

Step 4: Calculate the chi-square test statistic,

Step 5: Make the decision to reject or not to reject the null hypothesis.

Step 6: Summarize the results.

Anova Question (two-way ANOVA -with replication)

3)The following table show the standardized math exam scores for a random sample of students for three states. The sample included an equal number of eight-graders and fourth-graders.

	Tennessee	Florida	Arizona
Eight Grade	260	292	286
	255	260	274
	247	287	290
	277	280	269
	253	275	284
	260	260	297
Fourth Grade	275	270	286
	248	283	290
	250	280	295
	221	270	278
	236	283	258
	240	290	287

• Perform two-way ANOVA (with replication) using α = 0.05 by defining Factor A as the state and Factor B as to whether the student was an eighth-grader or a fourth-grader.
• Test the effects that the state and the grade of the student have on the standardized math score
• State sources of variation within sample .

STEP 1. For this activity you will observe (and/or participate in) a dining experience with others for the purposes of understanding how food and culture are interconnected. (You can participate in a meal or if you prefer you can view a meal on a television show or movie.)

STEP 2. Write notes on the types of communication you observe in the interactions during this meal (verbal, non-verbal, spatial, etc.) and record any messages about food, values, or culture that are visible.

Think about the type of language that individuals use, manners of speaking, tones of voice, loudness of voices, body language, gestures, and a variety of unspoken communication.

Are there cultural values being expressed regarding food and/or culture (Pay attention to what people say or express about the food they are eating- e.g., someone saying “I’m going to be BAD and eat ice cream tonight” or “We are being so good an healthy eating this salad”).

Does where and how the food is consumed convey any messages about culture? (e.g., eating from communal dishes vs. individual servings, or eating at formal table or in front of a TV).

Think critically about the messages being communicated through the meal. Reflect on what you observe. These notes are for you to use in your summary.

STEP 3. Summarize your observations and insights regarding the event you were observing and put it into context based on course material. Utilize the following questions to help construct your response. (Your write up should be 500-750 words. Include your word count in bold at the bottom.)

1. Describe the setting of your observation (when, where, what, who etc.).

2. How does the act of dining relate to culture?

3. What can be learned about American life and culture from observing dining?

4. How might dining illustrate microcultures within the larger “American” culture? (for example, there is a situation where only men eat together or there are restrictions about the types of food one can consume do to religious beliefs?)

5. What does the food itself reflect about this group of people?

6. Were there differences in communication styles or preparation and consumption of food based on gender, class, marital status, age, or race?

7. Were there messages about gender or status? Were their messages about age or family?

Reflect on any other significant elements of your observations. To receive full points it is important that you tie these observations into what you have learned about anthropology. Make direct references to course material.
