The standard deviation of the weights of elephants is known to be approximately 15 pounds. We wish to construct a 95% confidence interval for the mean weight of newborn elephant calves. Fifty newborn elephants are weighted. The sample mean is 244 pounds. The sample deviation is 11 pounds. State the distribution needed. Explain your reasoning. SE
Matthew wants to estimate the mean fat content of a pack of potato chips manufactured by UniBee Foods. He wants to be 90% confident that the estimate is accurate within 0.5 mg. Old records showed a 1.2 mg standard deviation. What should be the minimum sample size that he needs to construct this estimate?

What is the normalized z-score for a data point that has a value of 50 if the mean (Mu) is 560 and sigma is 55? This data point is taken from a total of 800 data point values .

It takes an average of 12.8 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will change if the patient is immediately told the truth about the injury. The EMT randomly selected 51 injured patients to immediately tell the truth about the injury and noticed that they averaged 14.1 minutes for their blood to begin clotting after their injury. Their standard deviation was 4.48 minutes. What can be concluded at the the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v Select an answer V Hj: ? v Select an answer V c. The test statistic ? v = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? va f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ...

A medical statistician wants to estimate the average weight loss of people who are on a new diet plan. In a preliminary study, he guesses that the standard deviation of the population of weight loss is about 8 pounds. How large a sample should he take to estimate the mean weight loss to within 4 pounds, with 97% confidence? Sample Size =
Cholesterol levels for teenage boys can be modeled by a normal distribution with mean 150 mg/dl and standard deviation 25 mg/dl. About 0.15% of 14-year-old boys have cholesterol levels less than what value? Use the empirical rule and do not round your answer.
In most cases of study, the statistical analysis is not giving the precise value of measurement but only giving the best estimation value of the precise value. Why is it so?
It takes an average of 10.2 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will decline if the patient is immediately told the truth about the injury. The EMT randomly selected 60 injured patients to immediately tell the truth about the injury and noticed that they averaged 10.1 minutes for their blood to begin clotting after their injury. Their standard deviation was 1.62 minutes. What can be concluded at the the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and altemative hypotheses would be: Họ: Select an answer H1: ? Select an answer c. The test statistic (please show your answer to 3 decimal places.) d. The p-value = e.
