Students do two tasks in a general chemistry class. These tasks scores show student performance on a scale of 0 to 100, with higher numbers indicating better performance.

Task 1: Scores on task 1 were normally distributed with a mean of 75 and a standard deviation of 5.

Task 2: Scores on task 2 were normally distributed with a mean of 80 and a standard deviation of 2.5.

Mia earned a 75 on task 1. What percentage of students did equal to or worse than Mia on task 1? ____ %

Students in a chemistry class convince their teacher to use the following "group grading" scenario. Students will all take the exam on their own; however, the grade they receive will be the mean of their test score with 4 other randomly selected classmates. Assume that the test scores for this particular exam are normally distributed with a mean of 74 and a standard deviation of 12 points. You need an 80 or better on this exam. What is the probability...

Show work a) A teacher informs her computational physics class (of 500+ students) that a test was very difficult, but the grades would be curved. Scores on the test were normally distributed with a mean of 25 and a standard deviation of 7.3. The maximum possible score on the test was 100 points. Because of partial credit, scores were recorded with 1 decimal point accuracy. (Thus, a student could earn a 25.4, but not a 24.42.) The grades are curved...

Scores of students in a large Statistics class are normally distributed with a mean of 75 points and a standard deviation of 5 points. Find the probability that a student scores more than 80 points If 100 students are picked at random, how many do you expect to score below 70 points? If top 10% of students obtain an A grade, how much should a student obtain to get an A grade. Suppose four students are picked at random, find...

1. An honors statistics instructor wanted to know if the mean performance of his 18 students was significantly better than the national average score. The mean score of the 18 students in his statistics class was 75. The national mean (i.e., µ) and standard deviation (i.e., σ) for the Statistics test was 69 and 11, respectively. Use α = .05. The fact that the population of scores on the exam were normally distributed suggests that which assumption was probably met?...

Test Scores A students scored 76 on a general science test where the class mean and standard deviation were 82 and 8 respectively; he also scored 53 on a psychology test where the class mean and standard deviation were 58 and 3 respectively.

A chemistry class had two tests. On the first test the mean score was 70 with a standard deviation of 10. On the second test the mean score was 60 with a standard deviation of 15. The correlation coefficient between the scores of the two tests was r = 0.6. We run a regression analysis with the first test score as the independent variable and the second test score as the dependent variable. We use the result to estimate the...

4. Exam scores in Professor Curm’s Calculus class are approximately normally distributed with a mean of 71 and a standard deviation of 13. Exam scores in Professor Polly’s Calculus class are approximately normally distributed with a mean of 83 and a standard deviation of 7. Assume each class is made up of random draws from the same underlying student population, and so comparable in principle .a) Compare a student who got a 68 in Curm’s class to one that got...

To determine student performance on a national test, a sample of 16 students is given the test. The average for the sample was 493 with a sample standard deviation of 56. Assume performance on the test is usually normally distributed, find a 90% confidence interval for the mean of the test.
