3.5 GRE scores, Part II: In Exercise 3.3 we saw two distributions for GRE scores: N(H=151,0=7) for the verbal section of the exam and N(u=153, o=7.67) for the quantitative section. Use this information to compute each of the following. Round all your answers to 2 decimal places. a) The score of a student who scored in the 75-th percentile on the Quantitative Reasoning section. b) The score of a student who scored worse than 70% of the test takers in the Verbal Reasoning section.
Nonparametric: A small study is conducted to compare birth weight in babies born to mothers who do not smoke to those that smoke more than ½ pack/day. Is there a significant difference between birth weights due to maternal smoking status? Use the Mann-Whitney U test with a 5% level of significance. What is U1 (non-smokers)?

Q You may need to use the appropriate appendix table or technology to answer this question. Last year, 50% of business owners gave a holiday gift to their employees. A survey of business owners conducted this year indicates that 35% plan to provide a holiday gift to their employees. Suppose the survey results are based on a sample of 60 business owners. (a) How many business owners in the survey plan to provide a holiday gift to their employees this year? business owners (b) Suppose the business owners in the sample did as they plan. Compute the p-value for a hypothesis test that can be used to determine if the proportion of business owners providing holiday gifts has decreased from last year. Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value = (c) Using a 0.05 level of significance, would you conclude that the proportion of business owners providing gifts decreased? Reject Ho. There is…

An article in a journal reports that 34% of American fathers take no responsibility for child care. A researcher claims that the figure is higher for fathers in the town of Littleton. A random sample of 225 fathers from Littleton, yielded 97 who did not help with child care.

The calculations for a factorial experiment involving four levels of factor A, three levels of factor B, and three replications resulted in the following data: SST = 286, SSA = 26, SSB = 24, SSAB = 178. Set up the ANOVA table. (Round your values for mean squares and F to two decimal places, and your p-values to three decimal places.) Source Sum of Variation of Squares Factor A Factor B Interaction Error Total ONL Degrees of Freedom Mean Square F p-value Test for any significant main effects and any interaction effect. Use α = 0.05. Find the value of the test statistic for factor A. (Round your answer to two decimal places.) Find the p-value for factor A. (Round your answer to three decimal places.) p-value = State your conclusion about factor A. Because the p-value > a = 0.05, factor A is not significant. Because the p-value ≤ α = 0.05, factor A is significant. Because the p-value > a = 0.05, factor A is significant. Because the p-value ≤ α = 0.05, factor A is not significant.
