A random sample of residents from various income brackets were asked their opinion On tax reform for the country of Guyana. The data gathered were analyzed by statistician and the results he obtained using MINITAB are shown below: Expected counts are printed below observed counts Low 26 (30.67) Middle (51.11) High (33.22) Total 115 Against 95 (69.33) 105 (115.56) 60 Total 260 Neutral 30 (20) (33.33) 20 (21.67) Total 130 Total 450 chi-sq 11.17 3.66 0.33 11.12 11.99 5.25 9.3 55.2 DF 22, p-value = 222 Carefully define the null and alternative hypotheses of the X2 test underlying the generation of the above table. Find the missing values and what is the conclusion of this test? Give reasons for your answer.

Step 1
The null hypothesis (H0) is that there is no association between income bracket and opinion on tax reform in Guyana. In other words, the distribution of opinions is the same across all income brackets. The alternative hypothesis (H1) is that there is an Show more…

Sixty-four students in an introductory college economics class were asked how many credits they had earned in college, and how certain they were about their choice of major. At α = .01, is the degree of certainty independent of credits earned? Credits Earned Very Uncertain Somewhat Certain Very Certain Row Total 0 to 9 13 8 2 23 10 to 59 9 5 10 24 60 or more 2 6 14 22 Column Total 24 19 26 69 (a) At α = .01, the hypothesis for the given issue is H0: Credits Earned and Certainty of Major are independent. multiple choice 1 Yes No (b) Calculate the chi-square test statistic, degrees of freedom, and the p-value. (Round your test statistic value to 2 decimal places and the p-value to 4 decimal places.) (c) Find the critical value of the chi-square for α = .01. (Round your answer to 2 decimal places.)

IV. The average New Orleans resident's income is thought to be about $27,000 -- undoubtedly due to the prevalence of low-paying service jobs. But what about the median income? A researcher hypothesizes that the median is less than $36,000. A random sample of residents yields 40 with incomes below $36,000 and 25 with incomes above $36,000. What is the result of the Sign Test, using the normal approximation to the binomial at α = 0.05? 1. In a clear and logically correct fashion, state the hypotheses of the test. (2) H₀: Hₐ: 2. Show all details in your calculation of the z test statistic. (12 -- 1,1,1,2,7) Your choice of S = n = μ = σ = z = (show calc. here -- as shown in class) = 3. Use the table or tech to find the p-value of the test to 4 decimals (must be consistent with z). (4) p = 4. Citing the above p-value (mention p and α), give a rejection decision. (3) Since 5. Give a complete sentence conclusion about the issue in question*, citing your answer to 4. (4) Since * You already made a rejection decision.

In Section 10.2, we tested hypotheses regarding a population proportion using a z-test. However, we can also use the chi-square goodness-of-fit test to test hypotheses with $k=2$ possible outcomes. In Problems 25 and $26,$ we test hypotheses with the use of both methods. According to the U.S. Census Bureau, $7.1 \%$ of all babies born are of low birth weight $(<5 \mathrm{lb}, 8 \mathrm{oz})$ An obstetrician wanted to know whether mothers between the ages of 35 and 39 years give birth to a higher percentage of low-birth-weight babies. She randomly selected 240 births for which the mother was 35 to 39 years old and found 22 low-birth-weight babies. (a) If the proportion of low-birth-weight babies for mothers in this age group is $0.071,$ compute the expected number of low-birth-weight births to 35 - to 39 -year-old mothers. What is the expected number of births to mothers 35 to 39 years old that are not low birth weight? (b) Answer the obstetrician's question at the $\alpha=0.05$ level of significance using the chi-square goodness-of-fit test. (c) Answer the question by using the approach presented in Section 10.2
