1. A local brewery distributes beer in bottles labeled 12 ounces. A government agency thinks that the brewery is cheating its customers. The agency selects 20 of these bottles, measures their contents, and obtains a sample mean of 11.7 ounces with a standard deviation of 0.7 ounce. Use a 0.01 significance level to test the agency's claim that the brewery is cheating its customers by underfilling the bottles.

A) critical value = -2.539; test statistic ≈ -1.917; fail to reject H0; There is not sufficient evidence to support the government agency's claim.
B) critical value = -2.528; test statistic ≈ -1.917; fail to reject H0; There is not sufficient evidence to support the government agency's claim.
C) critical values = ± 2.861; test statistic ≈ -1.917; fail to reject H0; There is not sufficient evidence to support the government agency's claim.
D) critical value = -2.539; test statistic ≈ -1.917; reject H0; There is sufficient evidence to support the government agency's claim.
E) critical values = ± 2.861; test statistic ≈ -1.917; reject H0; There is sufficient evidence to support the government agency's claim.
F) critical value = -2.539; test statistic ≈ -1.917; fail to reject H0; There is sufficient evidence to support the government agency's claim.
