Suppose that a researcher, using data on class size (CS) and average test scores from 100 third-grade classes, estimates the OLS regression.
TestScore = 515.1960 + (-5.7618) x CS, R^2 = 0.11, SER = 11.4
(20.1960) (2.3426)
1. The p-value for the two-sided test for the null hypothesis H0 : B1 = 0 is ? (Round to four decimal places)
2. The p-value for the two-sided test of the null hypothesis H0 : B1 = -5.5 ? (Round to four decimal places)

A school district undertakes an experiment to estimate the
effect of class size on test scores in second-grade classes.The
district assigns 20% of its previous year’s first graders to small
second-grade classes and 80% to regular-size classes. Students new
to the district are handled the same way : 20% are randomly
assigned to small classes and 80% to regular-size classes. At the
end of the second-grade school year,each student is given a
standardized test. Let Y denote the test score,X...

A school district undertakes an experiment to estimate the
effect of class size on test scores in second-grade classes. The
district assigns 50% of its previous year’s first graders to small
second-grade classes (18 students per classroom) and 50% to
regular-size classes (21 students per classroom). Students new to
the district are handled differently: 20% are randomly assigned to
small classes and 80% to regular-size classes. At the end of the
second-grade school year, each student is given a standardized...

Part A: Imagine a researcher thinks that using caffeine before a
test increases test scores. If they had the consent of all the
students in a 120-person class to participate in a study, a good
experimental design would follow which protocol?
a.
Collect information after the test from the students about the
caffeine they consumed the morning of the test. Regress that
against their test scores.
b.
Ask the whole class to drink16 ounces of coffee the morning of
the...

B.) 0.9987
C.) 0.0013
D.) 0
E.) 0.0026

The average IQ in America is 100. A researcher wants to test the
hypothesis that left-handed individuals have different IQs than the
average American. He administers an IQ test to 8 left-handed
individuals. They have mean 97.4 with a standard deviation of
13.
Test the hypothesis (=.05) that left handed individuals have
different IQs than the average Ameican.

A researcher is trying to predict test scores from student’s
level of stress. What is the standardized regression equation for
the following data taken from 10 students? The average level of
stress for students is 9.50 with a standard deviation of 2.76. The
average test score for students is 12.50 with a standard deviation
of 5.13. The correlation stress and test scores is 0.88.
