- ii only
- iii only
- i and ii
- i and iii

Can a pretest on mathematics skills predict success in a statistics course? The 82 students in an introductory statistics class took a pretest at the beginning of the semester. The least-squares regression line for predicting the score y on the final exam from the pretest score x was ŷ = 9.8 + 0.74x. The standard error of b1 was 0.41. (a) Test the null hypothesis that there is no linear relationship between the pretest score and the score on the...

Can a pretest on mathematics skills predict success in a statistics course? The 82 students in an introductory statistics class took a pretest at the beginning of the semester. The least-squares regression line for predicting the score y on the final exam from the pretest score x was ŷ = 9.4 + 0.78x. The standard error of b1 was 0.44.

The five parts are: i. Null Hypothesis: H0 : µ =5.2 ii. Alternative Hypothesis: HA : µ < 5.2 iii. Rejection Region: Reject H0 if t statistic <−t49,.05 =−1.677 iv. Test Statistics: t = Y−µ0 S/pn = 5−5.2 0.7/p50 =−2.0203 <−t49,.05 =−1.677 v. Conclusion. Reject H0 at α = 5%. The data support that the mean dissolved oxygen count of the water is less than the reading at this location over the past year. What is the p-value?

The National Center for Educational Statistics (NCES) reports that the average score for 12th graders who took the national reading test was 295 (on a scale of 1 to 500) (source: nces.ed.gov). A random sample of 100 12th graders in Blanchet County, Alabama, schools recently took the test. Students in the sample had an average score of 301. Given the following hypotheses, H0: ? ? 295 (The mean score for the population of Blanchet 12th graders is the same as...

Q1. Hypothesis testing using a Z test (14 points) A professor has been teaching introductory statistics for many years and the final exam performance (30 points total) has been very consistent from class to class and the scores have been normally distributed. Overall, the whole data base (i.e. population) of final exam scores has a mean (μ) of 20 points and a standard deviation (σ) of 5 points. Because 20 out of 30 is only about 67%, the professor would...
