Answer: The mean of this distribution = 61.95

The standard deviation of this sampling distribution  (i.e., the standard error= 0.048

Step-by-step explanation:

Given : Data from the U.S. Department of Education indicates that 59% of business graduate students from private universities had student loans.

i.e. proportion of business graduate students from private universities had student loans : p=0.59

sample size : n=105

Then , the mean of the distribution is given by :-

\mu= np = (105)(0.59)=61.95

∴The mean of this distribution = 61.95

Then standard deviation of this sampling distribution is given by :-

\sqrt{\dfrac{p(1-p)}{n}}\\\\=\sqrt{\dfrac{(0.59)(1-0.59)}{105}}\\\\=\sqrt{0.00230381}\\\\=0.047998015832\approx0.048

∴The standard deviation of this sampling distribution  (i.e., the standard error= 0.048
