- When creating a 99% CI based on data from one sample the size of n=31, which t value should be used?A market researcher wanted to evaluate the difference in credit charges for customers of Bracy’s. She randomly selected 100 customers and recorded their credit charges in December 2004 and January 2005. Is there evidence to show a difference in credit charges between the two months?Step 1: Step 2: α =Ho: H1:Step 3 Step 4 Step 5 Step 6 Difference: Dec. 2004 - Jan. 2005 Sample Diff: 280.74152 Std. Err: 99.50361 p-value: 0.0058lustration 19.33. An examination was given to 50 students at College A and to 60 students at Collage B. At A, the mean grade was 75 with S.D.=9. At B, the mean was 79 with SD=7. Is there a significant difference in the performance at the two Colleges at 5% level of significance?
- A researcher wonders whether younger mothers have babies that are significantly heavier or lighter than the population average of μ 7.25 pounds. The researcher collects data from N = 35 babies who were born to mothers between the ages of 16 and 18. The average weight for these babies was M = 7.15 pounds (SD = .6 pounds).An ANOVA produces an F-ratio with df = 1, 34. Could the data have been analyzed with a t test? What would the degrees of freedom be for a t statistic?A research study with N = 20 has a M = 4.86, μM = 4.54, and a s = 1.90. What is the t statistic
- Which of the following would probably NOT be a potential “cure” for non-normal residuals? Select one: a. Transforming two explanatory variables into a ratio. b. Removing large negative residuals. c. Removing large positive residuals. d. Using a procedure for estimation and inference which did not assume normality.For a repeated-measures experiment comparing two treatment conditions, the t statistic has a df of 17. How many subjects participated in this study?A manufacturer claims that 10% of women using the "pill" suffer from side effects. The Federal Drug Administration (FDA) believes that the manufacturer's claim is too low and decides to test the manufacturer's claim at a = 5 %. A random sample of 900 women who use the manufacturer's pill shows that 103 suffer side effects. The sample proportion of women who suffer effects from the pill is: a. 0.1144 Ob. 1.444 OC. 0.1000 d. 0.0144 O e. 0.0743

Your sample data produce the test statistic z = 3.03 . Find the pvalue accurate to 4 decimal places.The strength of concrete depends, to some extent, on the method used for drying. Two different drying methods showed the following results for independently tested specimens (measurements in psi): Do the methods appear to produce concrete with different mean strengths? Use α = 0.05 .
