Consider a general one-sided hypothesis test on a population
mean µ with null hypothesis H0 : µ = 0, alternative hypothesis Ha :
µ > 0, and Type I Error α = 0.02. Assume that using a sample of
size n = 100 units, we observe some positive sample mean x > 0
with standard deviation s = 5. (a) Calculate the Type II Error and
the power of the test assuming the following observed sample means:
(i) x =...

Use the ”test.vs.grade” data and test the null hypothesis that
the mean test score for the population is 70 against the
alternative that it is greater than 70. Find a p-value and state
your conclusion if α = 0.05. Repeat for the null hypothesis µ =
75.

Find confidence interval and perform a hypothesis test
for the mean of one population.
The economic dynamism, which is the index of productive growth
in dollars for countries that are designated by the World Bank as
middle-income are in table #1. Countries that are considered
high-income have a mean economic dynamism of 60.29. Do the data
show that the mean economic dynamism of middle-income countries is
less than the mean for high-income countries? Test at the 5%
level.

Consider the following hypothesis test. The null
hypothesis is "The mean body temperature for humans is 98.6 degrees
Farenheit." and the alternative hypothesis is "The mean body
temperature for humans differs from 98.6 degrees Farenheit." Answer
the following questions.
a. "The mean body temperature for humans in fact is
98.6 degrees Farenheit but the result of the sampling lead to the
conclusion that the mean body temprature for humans differ from
98.6 degrees Farenheit" is a
A. correct decision
