In order to test ?0:?=.5 vs. ??:?<.5 using the .10 level of
significance, a sample of ?=100 will be selected. Suppose that, in
reality, the population proportion is .4.
(a) The probability the test will commit a type II error
is .___
(b) The power of the test is ___ .
Independent random samples, each containing 50 observations,
were selected from two populations. The samples from populations 1
and 2 produced 30 and 25 successes, respectively.

For each of the 2 majors, conduct a full hypothesis test at the
10% significance level:
The mean ‘Cost’ for a college is $160,000.
2. For Business versus Engineering majors conduct a full,
two-sample, full hypothesis test at the 5% significance level
(assume the variances are not equal):The average ’30-Year ROI’ for
Business majors is less than for Engineering Majors.

A hypothesis test with a 5% level of significance is designed to
test the claim that the mean weight of a new breed of chickens is
greater than 6.00 pounds. A sample of 81 chickens is obtained and
their mean weight is 6.20 pounds with a sample standard deviation
of 0.50 pounds. No information is available concerning the standard
deviation of the whole population of the new breed. What is the
critical value (from Table A-3) and the test statistic...
