The researcher conducted a hypothesis test and found the 95%
confidence interval to examine whether there is a difference in
high school students completion rate in percent with respect to the
size of the teachers' salary (low or medium). The hypothesis test
result showed p-value of 0.59 and the CI was [-2.45, 4.45].
In the space provided below,
a) Explain whether the hypothesis test result and the confidence
interval are in agreement.

A researcher wants to test the hypothesis that increasing
temperature and physical exercise increases the body’s skin
conductivity (as measured by a galvanometer). A sample of 24 males,
all 21 years old is randomly selected, and the subjects are
randomly assigned to four treatment conditions. Group A is
subjected to high temperature and physical exercise (jogging in
place for 10 minutes). Their GSR (Galvanic skin response) scores in
decivolts are 9, 8, 8, 10, 7, and 8. Group B is...

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 social researcher wants to test the hypothesis that college
students may experience different levels of happiness depending on
how much they are using social media. She surveyed students about
the frequency of their social media use and their happiness. Among
10 heavy users, she found an average happiness score of 4.4 with a
variance of 4.3, whereas the 10 light users reported an average
happiness score of 6.5 with a variance of 3.4.

aged 30-39. State the null and alternative hypothesis for the
hypothesis test. Discuss the basic strategy for performing this
hypothesis test, based on independent samples.
