24.The owner of a fish market has an assistant who has determined that the weights of catfish are normally distributed, with mean of 3.2 pounds and a standard deviation of 0.8 pounds. If a sample of 64 fish yields a mean of 3.4 pounds, what is probability of obtaining a sample mean this large or larger?a)0.0001b)0.0013c)0.0228d)0.4987ANSWER:cTYPE: MC DIFFICULTY: ModerateKEYWORDS: sampling distribution, mean, probability

What percentage of samples of 4 fish will have sample means between 3.0 and 4.0 pounds?26.The use of the finite population correction factor, when sampling without replacement from finite populations, will27.For sample size 16, the sampling distribution of the mean will be approximately normally distributed28.The standard error of the mean for a sample of 100 is 30. In order to cut the standard error of the mean to 15, we woulda)increase the sample size to 200.b)increase the sample size to 400.c)decrease the sample size to 50.d)decrease the sample to 25.ANSWER:bTYPE: MC DIFFICULTY: Moderate KEYWORDS: standard error, mean

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
