Step-by-step explanation:
Let X be the no of vehicles that require warranty service within I year out of vehicles sold (9) yesterday.
Each vehicle is independent of the other to get warranty service
Hence X is binomial with p=8% = 0.08
So P(X=x) = ![9Cx (0.08)^x (1-0.08)^{9-x} ,x=0,1,2...9](https://tex.z-dn.net/?f=9Cx%20%280.08%29%5Ex%20%281-0.08%29%5E%7B9-x%7D%20%2Cx%3D0%2C1%2C2...9)
![a) P(X=0) = 0.472161\\b) P(x=1) = 0.3695](https://tex.z-dn.net/?f=a%29%20P%28X%3D0%29%20%3D%200.472161%5C%5Cb%29%20P%28x%3D1%29%20%3D%200.3695)
c) ![P(X=2) = 0.1285](https://tex.z-dn.net/?f=P%28X%3D2%29%20%3D%200.1285)
d) Mean = Mean of binomial = np =
![9(0.08) = 0.72](https://tex.z-dn.net/?f=9%280.08%29%20%3D%200.72)
Var (x) = npq = ![0.6624](https://tex.z-dn.net/?f=0.6624)
Std dev = square root of variance = 0.8139
Answer:
A.The data should be treated as paired samples. Each pair consists of an hour in which the productivity of the two workers is compared.
Explanation:
If the mean productivity of two workers is the same.
For a random selection of 30 hours in the past month, the manager compares the number of items produced by each worker in that hour.
There are two samples and the productivity of the two men is paired for each hour.
