850 x 0.05 = 42.5
850 + 42.5 = 892.5
She earned 42.5
And 892.5 she wardens at the end of four years
Answer:
0.0009
Step-by-step explanation:
![\mu=4](https://tex.z-dn.net/?f=%5Cmu%3D4)
![\sigma=0.55](https://tex.z-dn.net/?f=%5Csigma%3D0.55)
n = 8
This is the left tailed test .
The null and alternative hypothesis is ,
![H_0:\mu=4](https://tex.z-dn.net/?f=H_0%3A%5Cmu%3D4)
![Ha:\mu](https://tex.z-dn.net/?f=Ha%3A%5Cmu%20%3C4)
Test statistic = z=-3.12 from the table.
P(z <-3.12 ) = 0.0009
P-value =0.0009
There are 12 face cards in a deck, and one you draw the first face card there will be 11 left so:
(12/52)*(11/51)=132/2652=11/221
It would be x=-4 have a good day
