Question

The mean that college students owe on their credit cards is $896 with a standard deviation of $104. If all possible random samples of size 169 are taken from this population, determine: a) The mean and standard error of the sampling distribution of the mean b) The percent of sample means that fall between $884 and $900 c) Below what sample mean can we expect to find the lowest 30% of all sample means?

Step 1

Given: Mean (μ) = $896 Standard Deviation (σ) = $104 Sample Size (n) = 169 Mean of the sampling distribution of the mean (x̄): x̄ = μ = $896 Standard Error (SE) of the sampling distribution of the mean: SE = σ / √n SE = $104 / √169 SE = $104 / 13 SE = $8 **Mean Show more…
