Indicate the equation
1 answer:
Answer:
Slope - intercept form
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the point (2,-4) and slope
Equation of the straight line passing through the point (x₁, y₁) and slope 'm'
y - y₁ = m( x-x₁ )
y - (-4) = ( x-2)
⇒ 5( y+4) = 3(x-2)
⇒ 5 y +20 = 3x -6
⇒ 3x - 5 y -6-20 =0
⇒ 3 x -5y -26=0
<u><em>Step(ii):-</em></u>
Slope - intercept form
5 y = 3x -26

Answer:
The p value for this case would be given by"
For this case since the p value is higher than the significance level we don't have enough evidence to conclude that the true mean is significantly different from 6.5 lbs/square inch at 10% of significance. So then there is not enough evidence to conclude that the valve does not perform to the specifications
Step-by-step explanation:
Information given
represent the sample mean
represent the population deviation
sample size
represent the value that we want to test
represent the significance level
z would represent the statistic
represent the p value for the test
Hypothesis to verify
We want to verify if the true mean for this case is equal to 6.5 lbs/square inch or not , the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
(1)
And replacing we got:
