Answer: we are 95% confident that the total number of defective bulb
contained in the 1000 boxes shipped by this company is between 195.5 and 644.5
Step-by-step explanation:
The sample size n = 50
The population size N= 1000
The number of defective in the sample is 21.
Sample mean x bar= 21/50
=0.42
The standard deviation (sigma) is = 0.81
Calculating the confidence interval
By checking the attached picture below.
-np - 70 < 40
-np < 40 + 70
-np < 110
-np/-p < 110/-p
n < 110/-p
4w - 7k = 28
4w-4w-7k = 28 - 4w
-7k = 28 - 4w
-7k/-7 = 28-4w /-7
k = 28-4w/-7
Any number in fraction form is over 1, so for a negative number like -29 it would be 29 over negative 1, like this: 29/-1
To check: 6/(-8-4) = 4/-8
6/-12 = 4/-8
1/-2 = 1/-2
Therefore, <span>x = −8, non-extraneous</span>
Answer:
In this case, the mass of the car and the force exerted on it are provided as information. Therefore, the acceleration of the car is 0.5 m s−2 when its engine exerts a force of 600 N
