Answer:
Now we can decide based on the significance level . If we reject the null hypothesis and in other case we FAIL to reject the null hypothesis.
we see that so then we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly less than 15
we see that so then we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is NOT significantly less than 15
we see that so then we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is NOT significantly less than 15
Explanation:
For this case they conduct the following system of hypothesis for the ture mean of interest:
Null hypothesis:
Alternative hypothesis:
The statistic for this hypothesis is:
And on this case the value is given
For this case in order to take a decision based on the significance level we need to calculate the p value first.
Since we have a lower tailed test the p value would be:
Now we can decide based on the significance level . If we reject the null hypothesis and in other case we FAIL to reject the null hypothesis.
we see that so then we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly less than 15
we see that so then we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is NOT significantly less than 15
we see that so then we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is NOT significantly less than 15
Answer:
Out of the four options provided
option A. actuator
is correct
Explanation:
An actuator is the only device out of the four mentioned devices that provides power and ensures the motion in it in order to manipulate the movement of the moving parts of the damper or a valve used whereas others like ratio regulator are used to regulate air or gas ratio and none mof the 3 remaining options serves the purpose
Answer:
3180.86 Nm
Explanation:
Moment of inertia for shaft AB,
Torque in solid shaft AB will be given by
Where is shear stress, is polar moment of inertia for shaft AB, r is the radius of shaft B
The inner diameter of pipe CD can found considering that the thickness of pipe is 0.006 m hence diameter= 0.09-(2*0.006)= 0.078 m
Moment of inertia for shaft CD will be
Torque for shaft CD will be
and here r = 0.045 m
The minimum of the two torques is the largest torque that can be applied. Therefore, the torque to apply equals 3180.86 Nm
Answer:
175.99.136.0
Explanation:
175.99.138.0/21
Step 1: convert both the ip and the subnet mask to binary format
175.99.138.0 - 10101111.1100011.10001010.00000000
/21 : 255.255.248.0 - 11111111.11111111.11111000.00000000
step 2: perform the bitwise AND operation
In an AND operation, a result of 1 can only be gotten when both inputs are 1. Otherwise, the result will be 0.
10101111.1100011.10001010.00000000
11111111. 11111111. 11111000. 00000000
------------------------------------------------------
10101111. 1100011. 10001000. 00000000
step 3: convert the binary result back to base 10 number
10101111. 1100011. 10001000. 00000000
175.99.136.0
