1.In a statistics course, the average student result is 69.6% with the standard deviation of 9.4%. If Jake has completed the course with the score of 92.5%, what was Jake's z-Score

2.Find the probability to obtain 4 as the sum of dots, when two dice are tossed (one die is red and the other is blue). Round the answer to three decimal places. For example, for probability 0.05673, type 0.057.

3.Find the probability to obtain the sequence HTHT, when 4 coins are tossed one after another. Here H is "Head" and T is "Tail". Round your answer to 4 decimal places. For example, for probability 0.34123, type 0.3412

The semester average grade for a statistics course is 76 with a standard deviation of 5.5. Assume that stats grades have a bell-shaped distribution and use the empirical rule to answer the following questions (explain your responses with the help of a graph): 1. What is the probability of a student’s stat grade being greater than 87? 2. What percentage of students has stat grades between 70.5 and 81.5? 3. What percentage of students has stat grades between 70.5 and...

The average grade in a statistics course has been 70 with a standard deviation of 8. If a random sample of 51 is selected from this population, what is the probability that the average grade is more than 72? Use Appendix B.1 for the z-values. (Round your z-value to 2 decimal places and the final answer to 4 decimal places.) Probability
