Math 110 Module Update... Q Lab Assignment Name: Sections 8.1 Due Date: Math 34 This Lab is to be worked in the Math Lab when an instructor is present. You may work with your classmates, but be sure to complete your own assignment to turn in. To receive credit for this assignment you must log in at least 2 hours each week. Stating Conclusions About Claims. In Exercises 5-8, do the following: a. Express the original claim in symbolic form. b. Identify the null and alternative hypotheses. 5. Claim: 20% of adults smoke. A recent Gallup survey of 1016 randomly selected adults showed that 21% of the respondents smoke. 6. Claim: When parents use the XSORT method of gender selection, the proportion of baby girls is greater than 0.5. The latest actual results show that among 945 babies born to couples using the XSORT method of gender selection, 879 were girls. 8. Claim: The standard deviation of pulse rates of adult women is at least 50. For the random sample of adult females in Data Set 1 from Appendix B, the pulse rates have a standard devia- tion of 1 1.6.

In Exercises 5-8, identify the indicated values or interpret the given display. Use the nor- mal distribution as an approximation to the binomial distribution (as described in Part 1 of this section). Assume a 0.05 significance level and answer the following: a. Is the test two-tailed, left-tailed, or right-tailed? b. What is the test statistic? c. What is the P-value? d. What is the null hypothesis, and what do you conclude about it? e. What is the final conclusion? 5. Adverse Reactions to Drug The drug Symbicort is used to treat asthma. In a clinical trial of Symbicort, 18 of 277 treated subjects experienced headaches (based on data from AstraZeneca). The accompanying TI-83/84 Plus calculator display shows results from a test of the claim that less than 10% of treated subjects experienced headaches. TI-83/84 PLUS 1-PropZTest Prop 7/8, the test statistic is z = 2.88. Stating Conclusions. In Exercises 25-28, assume a significance level of a = 0.05 and use the given information for the following: a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Ho.) b. Without using technical terms, state a final conclusion that addresses the original claim. 26. Original claim: Fewer than 20% of M&M candies are green. The hypothesis test results in a P-value of 0.0721. PAGE 1098. Public Speaking A TNS poll of 1000 randomly selected adults showed that 460 of them say that public speaking is an activity that they dread most. Shown next is the StatCrunch display resulting from a test of the claim that fewer than half of adults say that public speaking is the activity that they dread most.
