3: The average cost of tuition and room and board at a small private college in the south-centralregion of the United States is reported to be S18,500 per term. A financial advisor believes thatthe average cost in Arkansas is less than S18,500. What are the null and alternative hypothesesfor this study?А.Họ: u = S18,500; H: u S18,500В.Họ: u2S18,500; H: u <$18,500С.Họ: u S18,500D.None of the above are correct.4: If the chosen significance level is a - .05, thenА.there is a 5% probability of accepting a true null hypothesis.В.there is a 5% probability of accepting a false null hypothesis.С.there is a 5% probability of rejecting a false null hypothesis.D.there is a 5% probability of rejecting a true null hypothesis.

Solve all problems using a chi square analysis. You must use statistics to support your answers. 1. Azookeeper hypothesizes that changing the intensity of the light in the primate exhibits will reduce the amount of aggression between the baboons. In exhibit A, with a lower light intensity, he observes 36 incidences of aggression over a one-month period. In exhibit B, with normal lights, he observes 42 incidences of aggression. Should he support or reject his hypothesis? Observed Expected (o-e)/e (6-42)^2/e I X=? Degrees of freedom = 1 Critical value ?
A Realtor believes that the average house price in Mission Viejo, California, is more than $480 thousand. %media:11excel.png% Click here for the Excel Data File a.

Independent studies show that 26 out of 40 r/s full-time students favor a shorter semester system, while 38 out of 50 r/s part-time students favor the same. Construct a 98% c.i. for the difference between the overall percentage of full-time students favoring a shorter semester system and that of part-time students.
5. A blood sugar reading above 300 mg/dL can be dangerous, according to the University of Michigan, which recommends immediately informing your doctor if you have two or more readings of 300 mg/dL in a row. In severe cases, very high blood sugar levels (well above 300 mg/dL) can result in coma. On the other side of the scale, a blood sugar reading below 70 mg/dL can be dangerous. If you experience more than two blood sugar readings below 70 mg/dL in a week, notify your doctor. Suppose that blood sugar levels are normally distributed with a mean of 100 mg/dl (milligrams per deciliter) and a standard deviation of 10mg/dL. David has a blood sugar level of 85 mg/dl. Calculate and David's z-score. What percentile is David in for his blood sugar level? What blood sugar readings would be more or less than 2.5 standard deviations from the mean? lio * f4 $ Download 101 4 % Search 5 Print ^ ◄0 6 . & 7 hp * + 8 f10 ► 11 о fu
1. In AP Econ, the total points accrued thus far is 800. The instructor has announced that there will be a total of 1000 points at the end of the semester. The final exam, therefore, is worth 200 points. Christina L currently has an average score of 87%. Is it possible for Christina L to squeak by with an A- in the class? Explain. Show your work. Assume an 89.5% in the class is considered an A-.
Late payment of medical claims can add to the cost of health care. Suppose 71.7% of the claims were paid in full when first submitted for one insurance company. The insurance company developed a new payment system in an effort to increase this percentage. A sample of 280 claims processed under this system revealed that 223 of the claims were paid in full when first submitted. Complete parts a and b below. a State the appropriate null and alternative hypotheses. Choose the correct answer below. OA. Ho p≤0.717 HA P>0.717 *** OC. Ho p=0.717 HA P#0717 OB.

1. Pg 221 Good for the gut? Is fish good for the gut? Researchers tracked 22,000 male physicians for 22 years. Those who reported eating seafood of any kind at least 5 times per week had a 40% lower risk of colon cancer than those who said they ate seafood less than once a week. Based on this study, is it reasonable to conclude that eating seafood causes a reduction in the risk of colon cancer? Explain.44
3. Scenario It is believed that large doses of acetaminophen (the active ingredient in over the counter pain relievers like Tylenol) may cause damage to the liver in nearly half of those tested. A researcher wants to conduct a study to estimate if the proportion of acetaminophen users who have liver damage is the same as previously reported. For participating in this study, he will pay each subject $20 and provide a free medical consultation if the patient has liver damage. Part A If he wants to limit the margin of error of his 98% conﬁdence interval to 2%, what is the minimum number of subjects he needs? (answer should be in the form of x,xxx) the minimum amount of money he needs to set aside to pay his subjects? $ (answer should be in the form of $xx,xxx) Part B The amount you calculated in Part A is substantially over his budget so he decides to use fewer subjects. Will this change increase or decrease the width of his conﬁdence interval? Will this new confidence interval be…
Consumers Energy states that the average electric bill across the state is $67.16. You want to test the claim that the average bill amount is greater than $67.16. The hypotheses for this situation are Null Hypothesis: u = 67.16, Alternative Hypothesis: u > 67.16. If the true statewide average bill is $51.28 and the null hypothesis is not rejected, did a type I, type II, or no error occur? a No error has occurred. b Type I Error has occurred. c Type II Error has occurred. d We do not know the p-value, so we cannot determine if an error has occurred.
