Step-by-step explanation:
- a day = 24 hours
- you know that there was 17 ¾ hours of no day light
- 17 ¾ = 17.75
- 24 - 17.75 = Daylight hours
- daylight hours = 6.25
Answer:
0.683
Step-by-step explanation:
We have to find P(-1<z<1).
For this purpose, we use normal distribution area table
P(-1<z<1)=P(-1<z<0)+(0<z<1)
Using normal area table and looking the value corresponds to 1.0, we get
P(-1<z<1)=0.3413+0.3413
P(-1<z<1)=0.6826
Rounding the answer to three decimal places
P(-1<z<1)=0.683
So, 68.3% of the z-scores will be between -1 an 1.
There are 12 boys 21/7=3 so 4(3)= 12
