Answer:

Step-by-step explanation:

2+3+4+5+6=20

20/20=4,000,000

2/20=?

2/20×4,000,000÷20/20=400,000

20/20=4,000,00

3/20

3/20×4000000÷20/20=600,000

20/20=4,000,000

4/20

4/20×4,000,000÷20/20=800,000

20/20=4,000,000

5/20

5/20×4,000,000÷20/20=1,000,000

20/20=4,000,000

6/20

6/20×4,000,000÷20/20= 1,200,000

2:3:4:5:6=400,000 :600,000: 800,000 : 1,000,000: 1,200,000

It has long been stated that the mean temperature of humans is 98.698.6degrees°F. However, two researchers currently involved i

const2013 [10]

Answer:

The claim is false that the mean temperature of humans is less than 98.6°F

Step-by-step explanation:

Claim :The mean temperature of humans is less than 98.6°F

$H_0:\mu \geq 98.6^{\circ}F\\H_a:\mu< 98.6^{\circ}F$

They obtained 200 measurements

Sample size n =200

x = 98.3°F

$\sigma = 11^{\circ}F$

Since n > 30

So we will use z test

Formula : $z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

Substitute the values in the formula :

$z=\frac{98.3-98.6}{\frac{11}{\sqrt{200}}}$

$z=−0.385$

Refer the z table for p value

p value = 0.3520

α= 0.01

p value > α

So, we accept the null hypothesis.

So, the claim is false that the mean temperature of humans is less than 98.6°F .

What Is the medían number of books<br>

TiliK225 [7]

Step-by-step explanation:

You didn't provide any numbers but in order to find the median of something you order a given list of numbers from least to greatest. After you've done this you find the number located in the middle of the number set. If there are two numbers in the middle then you add them together and divide that number by two.

Hope this helps.
