- An insurance investigator has observed that people with some astrological signs tend to be safer drivers than people with other signs. Using insurance records, the investigator classified 150 people according to their astrological signs and whether or not they were involved in a car accident during the previous 12 months. Do the following data indicate a significant relationship between sign and accidents? Test with a = .05. Libra Leo Gemini Accident 7 4 19 No Accident 73 46 1Suppose that a researcher is interested in the average standardized test score for fifth graders in a local school district. The fifth graders at a specific school would comprise a ___________ and their average test score would be a ___________.Researchers wanted to determine whether fence lizards learned to avoid fire ants. To determine this, they gathered lizards from eastern Arkansas (where there were no fire ants), and from southern Alabama (which had been invaded by fire ants). The lizards were then exposed to fire ants, and researchers measured how long (in seconds) it took the lizards to flee. What does each dot represent? Choose the best answer. Choice 1:A difference in time to flee for a single lizard from Alabama, and a single lizard from Arkansas, assuming the null hypothesis is true. Choice 2:A difference in mean response times for one sample of lizards from Alabama, and one sample of lizards from Arkansas, which was likely to occur if the null hypothesis is true. Choice 3:A difference in response times for two lizards in our sample. Choice 4:The proportion of all lizards who will free from fire ants. Which Choice is most correct and why?
- Strack, martin and Stepper (1988) reported that people rate cartoons as funnier when holding a pen in their teeth (Which force them to frown.) a researcher attempted to replicate this result using a sample of n = 30 adults between the ages of 32-37. For each person, the researcher recorded the difference between the rating obtained while smiling and the rating obtained while frowning. On the average cartoons were rated as funnier when the participants were smiling, with an average difference of 2.6 with SS = 200. a) Do the data indicate that the cartoons are rated significantly funnier when the participants are smiling? Use a two tailed test with α = 0.05. (Use the four logical steps in hypothesis testing) b) Compute for r2 to measure the size of the treatment effect. c) Write a sentence describing the outcome of the hypothesis test and the measure of effect size as it would appear in a research paper.Item 9 At a research facility that designs rocket engines, researchers know that some engines fail to ignite as a result of fuel system error. From a random sample of 40 engines of one design, 14 failed to ignite as a result of fuel system error. From a random sample of 30 engines of a second design, 9 failed to ignite as a result of fuel system error. The researchers want to estimate the difference in the proportion of engine failures for the two designs. Which of the following is the most appropriate method to create the estimate? A one-sample z-interval for a sample proportion A A one-sample z-interval for a population proportion B A two-sample z-interval for a population proportion C A two-sample z-interval for a difference in sample proportions D A two-sample z-interval for a difference in population proportionsA psychologist examining art appreciation selected an abstract painting that had no obvious top or bottom. Hangers were placed on the painting so that it could be hung with any one of the four sides at the top. The painting was shown to a sample of n = 50 participants, and each was asked to hang the painting in the orientation that looked correct. The following data indicate how many people chose each of the four sides to be placed at the top. Are any of the orientations selected more (or less) often than would be expected simply by chance? Test with a = .05. Top Up (correct) Bottom up Left side up Right side up 18 17 7 8
- Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x=104.18, y=105.25, r=0.892, P-value=0.000, and y=17.77+0.84x, where x represents the IQ score of the younger child. Find the best-predicted value of y given that the younger childhas an IQ of 108? The best-predicted value of y is?Produce a CROSSTAB for the variables DEGREE and MARHOMO. Before conducting the analyses, reverse code MARHOMO into R_MARHOMO so that 1 = Strongly Disagree; 2 = Disagree; 3 = Neither Agree nor Disagree; 4 = Agree; and 5 = Strongly Agree. Then, examine the relationship between these variables by testing both statistical significance and strength of association. Use chi-square for significance and choose the appropriate measures for strength of association (Phi, Cramer’s V, Lambda, or Gamma). Set alpha to .05. State the null and research hypotheses: H0: H1: What is the obtained chi-square value? What is the significance level (p-value) for the obtained chi-square? Should we reject or fail to reject the null hypothesis? Is there a statistically significant relationship between these variables? Which measure of association would be most appropriate for these variables? What is the value of the measure of association? Interpret your findings by explaining in full sentences whether there is a…Consider the next 1,000 95% CIs for \mu that a statistical consultant will obtain for various clients. Suppose the data sets on which the intervals are based are selected independently of one another. What is the probability that between 940 and 960 of these intervals contain the corresponding value of \mu?
