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...

We would like to conduct a hypothesis test at the 5% level of
significance to determine
whether hockey players weigh more on average than baseball players.
We record the
weights of a random sample of 12 professional hockey players and 7
professional baseball
players. Weights of athletes in both sports are known to follow
normal distributions.
Some summary statistics are given below:
Sport n x s d
Baseball 7 187.571 7.72
Hockey 12 195.583 18.39
Based on the data, we...

A 0.01 significance level is used for a hypothesis test of the
claim that when parents use a particular method of gender
selection, the proportion of baby girls is different from 0.5.
Assume that sample data consists of 78 girls in 169 births, so the
sample statistic of six thirteenths results in a z score that is 1
standard deviation below 0. Complete parts (a) through (h) below.
