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 (to nearest 0.001) for this hypothesis test?

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.
