Errors For each of the following situations, statewhether a Type I, a Type II, or neither error has beenmade. Explain briefly.a) A bank wants to see if the enrollment on their websiteis above 30% based on a small sample of customers. Ittests H0: p = 0.3 vs. HA: p 7 0.3 and rejects the nullhypothesis. Later the bank finds out that actually 28%of all customers enrolled.b) A student tests 100 students to determine whetherother students on her campus prefer Coke or Pepsiand finds no evidence that preference for Coke is not0.5. Later, a marketing company tests all students oncampus and finds no difference.c) A pharmaceutical company tests whether a drug liftsthe headache relief rate from the 25% achieved by the placebo. The test fails to reject the null hypoth-esis because the P-value is 0.465. Further testing shows that the drug actually relieves headaches in38% of people.
A test for "independence." You want to know if death within five years from a certain type of cancer is independent of gender. If the patient survives the first five years, she is considered "recovered." Consider the data: The logic for this test follows the pattern of the goodness-of-fit test. Here's how you do it: (a) Suppose that 84% of persons suffering from this type of cancer are still living after five years and that half are male and half female. This is our first approach to this data; the usual "test of independence" would not make these two assumptions. Determine the expected number, Ei , for each category under the assumption that recovery is independent of gender. (b) Evaluate Pearson's X2 statistic for part (a). (c) Based on part (b), does the data suggest that death rate for this cancer is independent of gender? (d) In part (b), what else does the data suggest beyond just independence? (e) Suppose you had not known the recovery rate for this…

Use the traditional method in testing the hypothesis in the problems below. In each problem, state the following:d. Make the decisione. Summarize the result The manager of the cosmetics section of a large department store wants to determine whether newspaper advertising really does affect sales. For her experiment, she randomly selects 15 items currently in stock and proceeds to establish a baseline. The 15 items are priced at their usual competitive values, and the quantity of each item sold for a 1-week period is recorded. Then, without changing their price, she places a large ad in the newspaper, advertising the 15 items. Again, she records the quantity sold for a 1-week period. The results follow.

The College Board reported that 58.7% of all students who took the 2010 AP Statistics exam earned scores of 3 or higher. One teacher wondered if the performance of her school was better. She believed that year's students to be typical of those who will take AP Stats at that school and was pleased when 34 of her 54 students achieved scores of 3 or better. Ca she clain that her school is better? To verify her clain, test the following hypotheses at Alpha =5%. Ho:P = 0.587 vs Ho:P>0.587

Identify the appropriate hypothesis test for each of the following research situations. A researcher conducts a between-subjects study to determine whether there is a significant difference in problem-solving ability between older adults who are generally happy and those who are generally unhappy. A researcher gives a questionnaire to a group of 30-year-old married adults, including questions to measure the stability of their own marriages and the stability of their parents’ marriages. The researcher would like to know whether the two variables are related. A researcher obtains a sample of 100 college students between 18 and 21 years old and a similar sample of 100 young adults who have no college experience. The researcher would like to know if there is a difference in the proportion of registered voters for the two groups.
spam. You've heard that at least 65% of the email you recieve through a certain email account is marked You suspect this is incorrect, so you keep track of the emails you receive on that account for the next week. In that time, you received 57 emails and 29 of them were marked as spam. State the null and alternative hypotheses of this test. Null Hypothesis (Ho): Alternative Hypothesis (HA): p? P? V To test our hypothesis, we will assume that p = Is the success-failure condition of the Central Limit Theorem satisfied? O No. Either np a. O No. The result is not significant because the p-value is
An anger-management courseclaims that, after completing its seminar, participants will lose their tempers less often. Always a skeptic, you decide to test this claim. A random sample of 12 seminar participants is chosen, and these participants are asked to record the number of times that they lost their tempers in the two weeks prior to the course. After the course is over, the same participants are asked to record the number of times that they lost their tempers in the next two weeks. The following table lists the results of the survey. Using these data, test the claim at the 0.01 level of significance assuming that the population distribution of the paired differences is approximately normal. Let d= (participants after completing the anger-management course) −(participants before completing the anger-management course).

A researcher hypothesizes that opera music will have an effect on test scores (but she is unsure whether they will increase or decrease). On a standardized reasoning test, known to have mu = 70 and sigma = 10, she has a sample of 30 subjects complete the test while listening to opera music. She then tallies up their scores, and finds a mean score for her sample of 66. Go through the steps of hypothesis testing and make a conclusion for the researcher about her experiment. Use a significance level of .05 (two-tailed). Sketch the chance distribution and shade your critical region.
3. A claim is made that the proportion of college students who have Netflix accounts is 0.85. Noah believes this claimed value is too high. He is able to survey a random sample of 240 college students, and he finds that the sample proportion who have Netflix accounts is 0.82. Noah proceeds to use this data to conduct a hypothesis test. Based on this information, which one of the following statements is correct? A. The p-value will be smaller than 0.01 but larger than 0. B. The p-value will be between 0.01 and 0.05. C. The p-value will be between 0.05 and 0.10. D. The p-value will be larger than 0.10.
