I'm interested in comparing the GPA of students at a junior college where I teach, with the national GPA average of all junior college students. I randomly select 22 students from my school (N = 22) and compare the mean of the 22 students with the national average. When I compare the two means I end up with a t-value of 2.761. Using an alpha value of .01, for a two-tailed test, what critical value do I find in Appendix B? (answer must have 3 decimal places)
In a test of H0: p = .43 versus Ha: p ≠ .43, a sample of size 1500 leads to a p-value of 0.087. Which of the following must be true if a = 0.05? A. The Ho should be rejected at the 5% level B. The Ho should fail to be rejected at the 5% level C. The Ho should be accepted at the 5% level

Use the following data to determine if drug B produces higher creatinine levels than drug A, assume the data is normally distributed. Write out the null and alternative hypothesis in words and symbols. Determine the critical value (use a significance level of 0.05) Calculate the test statistic, and determine if the results are significant or not. *Calculate by hand without using Excel or SPSS Creatinine levels (µmol/L) Drug A Drug B 48.2 52.3 54.6 57.4 58.3 55.6 47.8 53.2 51.4 61.3 52.0 58.0 55.2 59.8 49.1 54.8 49.9 52.6
An oil brand claims that the average mileage with one gallon of their gasoline is 25mi. You recorded the mileage of 10 independent cars with a gallon of said gasoline and obtained an average of 23.7mi. You want to determine if this is enough evidence to say that the brand is overestimating. Given a critical value of t = 0.822 and a significance level of 0.10, should we reject the H0?
Below are the results for a One Way ANOVA analysis. The critical value was 2.7 and alpha = .05. Which of the following statements is true? A) The result is statistically significant because F ratio of 3.83 > critical value of 2.7 B) The result is statistically significant because p < .05 C) The result is not statistically significant because p < .05 Both A & B
A researcher reports an F-ratio with dfbetween = 2 and dfwithin = 30 for an independent-measures ANOVA. a. How many treatment conditions were compared in the experiment? b. How many subjects participated ion the experiment?
Serum nitrite concentrations (in μmol/L) were compared between a group of unmedicated HIV+ subjects (n =7) and a control group (n = 10). The HIV+ distribution is strongly skewed.a) Use a Wilcoxon-Mann-Whitney U test to determine if there is convincing evidence at α = 0.05 thatserum nitrite levels differ between the two populations. b) What would have been the U test p-value if researchers had instead hypothesized that serum nitriteconcentrations would tend to be larger in the HIV+ population?
