Descriptive analysis revealed that the mean Test 3 score of all 63 students in Dr. Ron’s statistics courses was an 80. Similarly, the standard deviation for all students’ Test 3 scores was found to be 16. Assume the Test 3 scores are approximately normally distributed. Descriptive analysis indicated 89% of students passed Test 3. Suppose a random sample of 50 students is drawn and defined as the proportion of students in the sample who passed Test 3. 16. According to...

Suppose scores of students on a test are approximately normally distributed with a mean score of 65 points and a standard deviation of 8 points. It is decided to give A's to 10 percent of the students. Obtain the threshold score that will result in an A.

On a nationwide test taken by high school students, the mean score was 51 and the standard deviation was 11 The scores were normally distributed. Complete the following statements. (a) Approximately ?% of the students scored between 40 and 62 . (b) Approximately 95% of the students scored between ? and ?

The following information corresponds to students who Took Test 4. The mean score was 59.98 points and the standard deviation was 13.18. Assume scores for Test 4 are normally distributed. If 10 students are randomly selected, find the probability that the mean of their test score is greater than 56.

An administrator at a college claims that the mean SAT Mathematics score of incoming students is 520. You find that in a random sample of 45 incoming students, the mean SAT Mathematics score is 511 with a standard deviation of 48.65. Assume the population of scores are normally distributed. Suppose you perform a hypothesis test to determine whether the mean SAT Mathematics score of incoming students is less than 520. What is the P-value for this hypothesis test? Round the...

A principal claims the students in his school have above-average test scores for a particular standardized test. A sample of 50 students from his school were found to have an average test score of 77.2. The population mean for test scores for this particular test is 75, with a standard deviation of 9 (so we can assume that the population test score is normally distributed). Set up a hypothesis test to determine whether this principal’s claim is correct (use alpha...

(4)Five hundred students from a local high school took a college entrance examination. Historical data from the school record show that the standard deviation of test scores is 40. A random sample of thirty- six students is taken from the entire population of 500 students. The mean test score for the sample is three hundred eighty. Find (a) 95% confidence interval for the unknown population mean test score. (b) 95% confidence interval for the unknown population mean test score if...
