Explain whether or not you consider the follow
statement to be a scientific hypothesis:
"Students that attend class score higher than kids who dont attend
class."
Yes. This can be a hypothesis. As this statement can be tested based on a data. Data can be collected regarding the attendance and marks obtained by each student. Then statistical analysis can be applied.
Alternative hypothesis can also be formulated. If the said statement is not proven given the percentage confidence required, alternative hypothesis will be true.
Collect data regarding attendance and marks per student and draw a graph (Normal distribution).
Explain whether or not you consider the follow statement to be a scientific hypothesis: "Students that...
A researcher wants to determine whether high school students who attend an SAT preparation course score significantly different on the SAT than students who do not attend the preparation course. For those who do not attend the course, the population mean is 1050 (? = 1050). The 16 students who attend the preparation course average 1150 on the SAT, with a sample standard deviation of 300. On the basis of these data, can the researcher conclude that the preparation course...

A researcher is interested in whether students who are musicians have higher intelligence scores than those in the general population. The researcher predicts that playing a musical instrument is associated with higher intelligence test scores. The researcher selects a sample of 75 musicians from local high schools and gives them an intelligence test. She compares their average intelligence to that of students in the general population and finds that zobt = +1.92. This is a _____ test and the researcher...
A researcher is interested in whether using your finger to follow the words you are reading increases reading speed. He has students complete a reading speed test, first without using their finger to follow the words, and then again white using their finger to follow the words. In the beginning of the study, a randomly selected group of 64 students scored an average of 256 words per minute on the reading speed test. Since the sample size is larger than...
Examine the given statement, then identify whether the statement is a null hypothesis, an alternative hypothesis or neither. The more college courses a person has, the higher their salary will be. PS: It's not an Alternative hypothesis. Question options: A) Neither B) Null hypothesis
Scenario A: A professor is interested in whether taking online quizzes over a chapter before discussing the chapter in class will improve students’ test performance. The professor is interested in examining the testing effect, the finding that taking a memory test not only assesses what one knows, but also enhances later retention. The professor hypothesizes that students who take chapter quizzes will score higher on the midterm exam than students who do not take chapter quizzes. Design and describe an...
These days l, many students take a prep course to improve their standardized testing scores. If the average SAT score is 1040 and there are 36 students who took the test-prep class with an average score was 1085 with a standard deviation of 12, is the class effective? ( Consider "effective" in this case to mean significant with .03) Explain your reasoning using hypothesis testing including all relevant values.
A public school system wanted to know whether the reading levels of the students at two of its schools were different. The study that was conducted tested an enormous number of students, and concluded that students attending School A scored significantly higher than those attending School B. However, the difference between the means of the two schools was very small. What should you conclude regarding the difference in reading levels between the two schools? Explain your conclusion. Write your answer...
want to test the hypothesis that students who study one week before score greater than students who study the night before, giving you the following hypotheses: Null Hypothesis: H1 = H2, Alternative Hypothesis: H1 > H2. A random sample of 31 students who indicated they studied early shows an average score of 86.19 (SD = 4.358) and 35 randomly selected procrastinators had an average score of 84.58 (SD = 6.631). Perform a two independent samples t-test assuming that early studiers...
