Suppose X = GPA for TAMU students.

What would happen if you sampled every student at TAMU, so that the sample size n equals the number of students at TAMU? Consider the distributions of the sample and the sampling distribution of the sample mean. Choose all of the following that are true.

a) The data distribution would match the population distribution for every sample.

b) The sampling distribution would be the same as the population distribution.

c)The sampling distribution would have a variance of zero.

d)The data distribution would have a variance of 0 for each data set selected.

e) The variance of the sampling distribution would be larger than the variance of the population distribution.

What would the sampling distribution of the sample mean look like if we take a sample of size n = 1? Choose all of the following that are true.

a) The variance of the sampling distribution would be larger than the variance of the population distribution.

b) The sampling distribution would be the same as the population distribution.

c)The data distribution would have a variance of 0 for each data set selected.

d) The data distribution would match the population distribution for every sample.

e)The sampling distribution would have a variance of zero.

    A teacher decided to bring a jar of 530 pieces of small candy to his 100-student classroom so students could practice estimation. The students were told that whoever had the closest guess would win the candy. Suppose we took a random sample of one third of the students and calculated the sample mean of their guesses. The distribution of individual guesses had a mean of 400 pieces of candy and a standard deviation of 3,000 pieces of candy (the students...
