Recorded math scores of 200 students and like to know if their average is significantly (a = 0.05) different from the university average of 60. The average score of the 200 students is 62.8 and the standard deviation is 12.
a) What are the null and the alternative hypothesis?
b) What do you conclude?
Homework Answers

Test the claim that the mean GPA of Orange Coast students is significantly different than the mean GPA of Coastline students at the 0.05 significance level. The null and alternative hypothesis would be: The test is: two-tailed, right-tailed, left-tailed? The sample consisted of 60 Orange Coast students, with a sample mean GPA of 3.38 and a standard deviation of 0.04, and 60 Coastline students, with a sample mean GPA of 3.41 and a standard deviation of 0.06. The test statistic...

We know that, in the population, the average memory span (number of items a person can recall) is 7, with a standard deviation of 2. We want to know if the herb gingko biloba can really enhance a person’s memory. We get a sample of 25 students and have them take the herb for one month and then test their memory span. What null hypothesis would we test? What is the alternative hypothesis? We know that, in the population, the...

A math teacher claims that she has developed a review course that increases the scores of students on the math portion of a college entrance exam. Based on data from the administrator of the exam, scores are normally distributed with mu equalsμ=519519. The teacher obtains a random sample of 20002000 students, puts them through the review class, and finds that the mean math score of the 20002000 students is 525525 with a standard deviation of 114114. Complete parts (a) through...

A math teacher claims that she has developed a review course that increases the scores of students on the math portion of a college entrance exam. Based on data from the administrator of the exam, scores are normally distributed with mu equals510. The teacher obtains a random sample of 1800 students, puts them through the review class, and finds that the mean math score of the 1800 students is 515 with a standard deviation of 111.

Do students tend to improve their Math SAT scores the second time they take the test?...
Do students tend to improve their Math SAT scores the second time they take the test? We take a random sample of 100 hundred students who took the test twice. The mean score and the standard deviation of these 100 students on the first try are 500 and 90 respectively; the mean score and the standard deviation of these 100 students on the second try are 530 and 92 respectively. We also examine the change in Math SAT score (second...

A sample of 50 third-grade students had a average of 78 on a math proficiency test, with a sample standard deviation of 12. Is there enough evidence to conclude that the third-grade sample mean is different from the third-grade population mean of 67? Assume a 0.02 significance level. Use the Critical Value Method of Testing (this means NO P-Values!). In your work space below, you will need to have - 1. The null hypothesis, Ho 2. The alternative hypothesis, H1...

The scores in a Math Contest follow the Gaussian Distribution. Arvind scores 75 out of 100. The average score for the test is 60. The Standard deviation is 15. The top 10 percent of the Contest are eligible for Scholarship. What is the Least score needed to qualify? Will Arvind qualify? What percentage of students scored lower than Arvind?

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. A sample of 10 children in a gifted learner program are found to have a mean IQ of 106. Use a z-test to determine if this is significantly different from the normal population mean. What are your specific null and alternative hypothesis? Z=+ - 1.96 standard deviation m= 4.743 Z= 1.26 Will you reject or retain the null hypothesis? We will retain the null...

At a local university, a sample of 49 evening students was selected in order to determine whether the average age of the evening students is significantly different from 21. The average age of the students in the sample was 23.25 years. The population standard deviation is known to be 7 years. Determine whether or not the average age of the evening students is significantly different from 21. Use a .1 level of significance. Calculate the critical value. I know the...
