Tutoring Services: The Community College Survey of Student Engagement reports that 46% of the students surveyed rarely or never

use peer or other tutoring resources. Suppose that in reality 40% of community college students never use tutoring services available at their college. In a simulation we select random samples from a population in which 40% do not use tutoring. For each sample we calculate the proportion who do not use tutoring. If we randomly sample 500 students at a time, what will be the mean and standard error of the sampling distribution of sample proportions

Answer: Mean = 0.40 and  standard error = 0.0219 of the sampling distribution of sample proportions.

Step-by-step explanation:

Given : The proportion of community college students never use tutoring services available at their college: p= 0.40

Mean of the sampling distribution of sample proportions  = p = 0.40

Since sample size : n= 500

Standard error = \sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.40(1-0.40)}{500}}

=\sqrt{\dfrac{0.24}{500}}

=\sqrt{0.00048}=0.0219

Hence, Mean = 0.40 and  standard error = 0.0219 of the sampling distribution of sample proportions.

Help pls!!!how to solve it​
Mariana [72]

Answer:

q = 5/6

Step-by-step explanation:

First, we distribute.

16q - 10 = 4q

Then, we combine like terms.

-10 = 4q - 16q

-10 = -12q

Finally, we divide -12 on both sides.

5/6 = q, or q = 5/6

Hope this helps ^^

levacccp [35]

Answer:

2815 views

Step-by-step explanation:

Given :

⇒ Views on first day = <u>500</u>

⇒ Rate of increase = <u>28%</u>

============================================================

Creating a function :

⇒ Let y be the <u>total number of views</u> and x be the <u>number of days since posted</u>

⇒ y = 500 (1 + 0.28)ˣ = y = 500(1.28)ˣ

============================================================

Solving :

⇒ y = 500(1.28)⁷

⇒ y = 500(5.62949953)

⇒ y = 2815 views (nearest whole number)
