This test: 20 point(s) Question 10 of 20 possible This question: 1 Submit test point(s) possible Here are summary statistics for randomly selected weights of newborn girls: n = 36, x = 3197.2 g, s = 692.6 g. Use a confidence level of 95% to complete parts (a) through (d) below. g < H< [ g Round to one decimal place as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. O A. There is a 95% chance that the true value of the population mean weight of newborn girls will fall between the lower bound and the upper bound. O B. One has 95% confidence that the sample mean weight of newborn girls is equal to the population mean weight of newborn girls. O C. Approximately 95% of sample mean weights of newborn girls will fall between the lower bound and the upper bound. O D. One has 95% confidence that the interval from the lower bound to the upper bound contains the true value of the population mean weight of newborn girls. an example Get more help - NextThis test: 20 point(s) < Question 11 of 20 possible This question: 1 Submit test point(s) possible Determine whether the following procedure results in a binomial distribution or a distribution that can be treated as binomial (by applying the 5% guideline for cumbersome calculations). If it is not binomial and cannot be treated as binomial, identify at least one requirement that is not satisfied. Surveying 3930 homemakers and recording how satisfied they are with their toaster on a scale from 1 to 5 Choose the correct answer below. O A. It is binomial or can be treated as binomial. O B. It is not binomial because there are more than two possible outcomes. O C. It is not binomial because the probability of success does not remain the same in all trials. O D. It is not binomial because there are more than two possible outcomes and the trials are not independent. extbook Get more help - Next 99+ wThis test: 20 point(s) Question 10 of 20 possible This question: 1 Submit test point(s) possible Here are summary statistics for randomly selected weights of newborn girls: n - 36, x = 3197.2 g, s = 692.6 g.
