Use the following data to conduct a one-sample t test (
with alpha= 0.05) to determine if the score on a standardized test
( for scores that a are normally distributed) with a known
population mean of 100 is influenced by a new instructional
method:
95, 105, 110. 90, 120, 110, 100, 95, 105, 125, 80, 100, 120,
115, 115, 120, 120, 105.

Suppose that we wish to test a claim that a sequence of sample
data was produced in a random manner, and suppose that each data
value belongs to one of two categories. Let n1n1 be the number of
elements in the sequence that belong to the first category, n2n2 be
the number of elements in the sequence that belong to the second
category, and GG be the number of runs in such a sequence.

Problem #1
1) Conduct a single-sample t-test for the following data set,
assuming that µ = 25.00.
20 45 10 25 35 15 19 22 35 10 15 30
2) Determine the critical values (for an alpha of .05) that you
should use to evaluate this t-score.

To conduct a two-sample test of hypothesis with independent
samples, what must be true?
a) The sample size from each population must be the same.
b) The members in both populations must be related.
c) The populations must come from different geographic
areas.
d) Both samples must measure the same parameter (wages, age,
preference, etc.) from their respective populations.

Use "PLUC" data and the description for the dataset on the
blackboard. Conduct a two sample independent t test to test if the
population means of heights of male is higher than that of female.
Use R to calculate the p-value.
