As the first students begin to turn in their completed exams, she wants to get a feel for what kind of grades she can expect from her students. She quickly grades the first 16 exams that are submitted while the teaching assistant monitors the students who are still working. Professor Maryam finds that the mean exam score for this sample of 16 students is 77.3 points. The standard deviation of their scores is 6.4 points. Maryam expects that the scores for all students in her lecture will be normally distributed. She plans to use this information to construct a one-sample f confidence interval for #, the mean exam score for all students in her lecture. Have the conditions for this confidence interval been met? .

Hint Check Answer Question 13 of 14 > Attempt 2 Carly and Maysem plan to be preschool teachers after they graduate from college. To prepare for snack time, they want to know the mean number of goldfish crackers in a bag of original-flavored goldfish. To estimate this value, they randomly select 12 bags of original-flavored goldfish and counted the number of crackers in each bag. Here are their data: The 95% confidence interval BFW Publishers for the true mean number of crackers in a bag of original goldfish is (326.66, 336.17). Explain two ways that Carly and Maysem could reduce the margin of error of their estimate. Why might they object to these changes? Check all true statements. To reduce the margin of error, Carly and Maysem could To reduce the margin of error, Carly and Maysem could decrease the confidence level. increase the sample size. To reduce the margin of error, Carly and Maysem could They may not want to decrease the confidence level increase the confidence level. because it is desirable to have a high degree of confidence that the population parameter has been captured by the interval. about us | careers | privacy policy | terms of use contact us Sign out Apr 18 1:11 US $ 8 Ources Lx Give Up?
