Question 13 (1 point) Saved Use the confidence level and sample data to find a confidence interval for estimating the population μ. Round your answer to the same number of decimal places as the sample mean. A laboratory tested 82 chicken eggs and found that the mean amount of cholesterol was 228 milligrams with σ-19 milligrams. Construct a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs. (1224 mg < μ < 232 mg 223...

1.) Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). The test statistic in a two-tailed test is z = 1.95. Group of answer choices 0.0256; reject the null hypothesis 0.9744; fail to reject the null hypothesis 0.0512; reject the null hypothesis 0.0512; fail to reject the null hypothesis 2.)
