A group of students were administered two IQ tests. One was based on language and meant to measure their “verbal IQ.” The other contained problem solving with numbers and puzzle exercises with little verbal content – it was meant to measure their “performance IQ.” Scores on the tests were:
Verbal IQ Performance IQ
90 92
105 115
95 98
93 103
92 99
96 95
Use the appropriate t-test model to test the null hypothesis that verbal and performance are the same for the population of students.
Use a one-tailed test at the 0.05 level of significance.

19. Are you smarter than your older brother? In a study of birth order and intelligence, IQ tests were given to 18- and 19-year-old men to estimate the size of the difference, if any, between the mean IQs of firstborn sons and of secondborn sons. The following data for 10 firstborn sons and 10 secondborn sons are consistent with the means and standard deviations reported in the article. It is reasonable to assume that the samples come from populations that...

CSC888 has 4 people. Each person needs to take 3 tests. Create a 4-by-3 two-dimensional array to store the test scores. Ask the user to enter test scores one at a time to populate this array. Once the whole array is filled, do the following two things. (1) For each student, display her test scores and the average of the three tests. (2) For each test, display student scores and the average of the four students. The following shows a...

In what follows use any of the following tests/procedures: Regression, confidence intervals, one-sided t-test, or two-sided t-test. All the procedures should be done with 5% P-value or 95% confidence interval. Open Weight_vs_IQ data. SETUP: Common sense dictates that a person’s IQ and Weight should not be related. However, one never knows until one examines the data. Given the data (IQ and weight for 29 students) your job is to check if the common sense assumption is reasonable or maybe it...

3. [25 marks] Some female psychology students were investigating
whether intelligence depends on brain size. They each took a
standard test that measured verbal IQ and also underwent an MRI
scan to measure their brain size.
The variables are:
IQ Result of the verbal IQ test. IQ is measured on an artificial
index scale, usually meant to have an average value of 100.
BrainV Brain volume measured in thousands of ‘pixels’. The size
of a pixel derives from the two-dimensional...
