Anestetic [448]

Answer:

a) Dependent

b) H0: µd = 0

Ha: µd > 0

c) Stat --> Basic Statistics ----> Paired t. then select samples 1 , 2 to get the required output

d) Not enough data

Step-by-step explanation:

Using values found in MINITAB 19

a) The samples are dependent and this is because the title of the test is the same ( i.e. A group of students given the LSAT )

b) Appropriate hypothesis

H0: µd = 0

Ha: µd > 0

c) The Minitab procedure to be used to test the hypothesis is

click on Stat --> Basic Statistics ----> Paired t. then select samples 1 , 2 to get the required output

d) Not enough data to create a probability plot

Nadya [2.5K]

Answer:

$\frac{dy}{dt} = 102$

Step-by-step explanation:

step(i)

Given function y = 3 x³ - 2 x ... (i)

Differentiating equation (i) with respective to 'x'

$\frac{dy}{dx} = 3 (3 x^{2} ) - 2(1)$

Given x = -2

$(\frac{dy}{dx} ) x_{=-2} = 3 (3 (-2)^{2} ) - 2(1)$

$(\frac{dy}{dx} ) x_{=-2} = 36 -2 =34$

Step(ii):-

we know that

$\frac{dy}{dx} = \frac{\frac{dy}{dt} }{\frac{dx}{dt} }$

Given $\frac{dx}{dt} = 3 and \frac{dy}{dx} = 34$

$\frac{dy}{dx} = \frac{\frac{dy}{dt} }{\frac{dx}{dt} }$

substitute values $\frac{dx}{dt} = 3 and \frac{dy}{dx} = 34$

⇒ $34 = \frac{\frac{dy}{dt} }{3 }$

cross multiplication , we get

$\frac{dy}{dt} = 34( 3 ) = 102$

Final answer:-

$\frac{dy}{dt} = 34( 3 ) = 102$
