Data from the U.S. Department of Education indicates that 59% of business graduate students from private universities had studen

t loans. Suppose you randomly survey a sample of graduate business students from private universities. Consider the sampling distribution (sample size n = 105) for the proportion of these students who have loans.
What is the mean of this distribution? (Enter your answer accurate to two decimal places.)

What is the standard deviation of this sampling distribution (i.e., the standard error)?

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

Lily bought 25.29 pounds of grapefruit. The lightest grapefruit weighed 1.4 pounds. The heaviest grapefruit weighed 1.6 pounds.
Gemiola [76]

Answer:

B

Step-by-step explanation:

GIven that the lightest is 1.4 and the heaviest is 1.6, this implies that ALL the fruit must weigh between 1.4 and 1.6.

This also implies that the average weight of the fruit must also be between 1.4 lb and 1.6 lb.

recall that : average weight = total weight / number of fruit

we are given than total weight = 25.29 lb, so

average weight = 25.29 / number of fruit

Just go down the choices and test which choice gives an average weight between 1.4 and 1.6 lbs.

Choice A: number of fruit = 19

average = 25.29 / 19 = 1.33  (outside of range, not the answer)

Choice B: number of fruit = 17

average = 25.29 / 17 =1.49   (within range , possible answer)

Choice C: number of fruit = 10

average = 25.29 / 10 = 2.529 (outside of range, not the answer)

Choice D: number of fruit = 50

average = 25.29 / 50 = 0.5058  (outside of range, not the answer)

From the above, we can see that only B gives an average between 1.4 and 1.6 lb.

Eastville has a population of 32,000 and is gaining 500 people per year. Lakeside has a population of 45,000 and is losing 1,000
Semenov [28]

Answer:

  in about 8 2/3 years

Step-by-step explanation:

The population difference of 13000 people is being erased at the rate of 1500 people per year. It will be gone in ...

  13000/1500 = 26/3 = 8 2/3 . . . . years

The population of Lakeside will be 45000 -8667 = 36333 at that time. Eastside's population will be the same.

Eastville and Lakeside will both have populations of 36,333 in 8 2/3 years.
