Answer:    Two-tailed test.

Population mean is the parameter which is tested.

Step-by-step explanation:

Given :   H_0: \mu=105

H_1:\mu\neq105

We know that , the alternative hypothesis (H_1) indicates kind of the hypothesis test we need to perform whether ​left-tailed, right-tailed, or​ two-tailed.

Here, the alternative hypothesis (H_1) is two-tailed, so the hypothesis test is a two-tailed test.

Also, the parameter present in the hypothesis is \mu which is a symbol to represent the population mean.

Thus , Population mean is the parameter which is tested.

What percent of 2000 is 160?<br> Show work
ArbitrLikvidat [17]

Hello from MrBillDoesMath!

Answer:

.08%

Discussion:

Let the percent be denoted "p". Then

2000 * p% = 160 =>     ( as p% = p/100)

2000* p/100 = 160 =>

20p = 160 =>

p = 8 or .08%

The histogram below shows information about the number of books students read in a month:
TiliK225 [7]
This information provides the number of students who read a certain range of books. Those ranges are provided 0 to 4 (inclusive) 5 to 9 and 10-14.

Since 9 books or more covers two bins, this cannot be the answer. 

The information doesn't offer specific values just ranges, so both the mean and median cannot be determined. 

So the answer is C, the number of students who read 4 books or fewer.

Plz help me ASAP thx.

Use the Pythagorean theorem:


a^2+(2\sqrt3)^2=(4\sqrt3)^2\\\\a^2+2^2(\sqrt3)^2=4^2(\sqrt3)^2\\\\a^2+4\cdot3=16\cdot3\\\\a^2+12=48\ \ \ \ |-12\\\\a^2=36\to a=\sqrt{36}\\\\\boxed{a=6\to C.}



Used:


(a\cdot b)^n=a^n\cdot b^n\\\\(\sqrt{a})^2=a
