Answer:

Y=3

Step-by-step explanation:

You go over to the X axis, find -2 and go up the line vertically until you touch the black line going across. You look to the right and see it says 3. So 3 is your answer

Convert 17/4 to a decimal

Gelneren [198K]

Multiply nominator and denominator by 25:

$\dfrac{17}{4} = 4 \dfrac{1}{4}=4 \dfrac{1 \cdot 25}{4 \cdot 25}=4 \dfrac{25}{100}=4.25$

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 .
