Write a simulation in R that shows the distribution of the
t-‐test statistic for a two-‐sample t test when the null
hypothesis is true (i.e. when H0: µ1 -‐ µ2 = 0 is true). To do
this, you should use a for loop that repeatedly performs t-‐tests
comparing sample means of data that come from distributions with
the same population mean and standard deviation. Use rnorm() to
take samples, t.test() to perform the t-‐ tests, and use
“$statistic” to extract...

Of the following statements, which are correct?
1) Kolmogorov-Smirnov test can be used to compare the medians of
two continuous populations based on two independent samples from
the two populations
2) Sample data on one variables collected from each of n
randomly selected subjects at two distinct time points are
considered two independent samples.
3) Wilcoxon ranks-sum test can be used to compare population
medians using paired random samples
4) Fisher's exact test can be used to see if proportions...

An experiment was carried out to compare recall ability when
reading electronically compared to hard copy. Thirty students from
a first-year university English class agreed to participate. Each
student was shown a randomly generated list of 40 five-letter words
on a tablet and given 2 minutes to memorise them. They were then
given 4 minutes to write down as many of the words as...

Use the normal distribution and the given sample results to
complete the test of the given hypotheses. Assume the results come
from a random sample and use a 5% significance level.

Use the normal distribution and the given sample results to
complete the test of the given hypotheses. Assume the results come
from a random sample and use a 5 % significance level:
a) Test H 0 : p = 0.5 vs H a : p > 0.5 using the sample
results p ^ = 0.60 with n = 50
b) Test H0 : p=0.3 vs Ha : p<0.3 using the sample results
p^=0.20 with n=198
c) Test H0 : p=0.75...

Use the t-distribution and the sample results to
complete the test of the hypotheses. Use a 5% significance level.
Assume the results come from a random sample, and if the sample
size is small, assume the underlying distribution is relatively
normal.
Test H0 : μ=100 vs Ha : μ<100 using the sample results x¯=91.7,
s=12.5, with n=30.
