I'm guessing you are using military time.
Note, 23:00 is the same as 11:00 pm, and 12:20 is the same as 12:20 pm
Also note: 1 hour = 60 minutes
1) Change 1 hour inside 23:00 to minutes
23:00 = 22:60
Subtract
22:60 - 12:20 = 10:40
The time between 12:20 and 23:00 is 10 hours and 40 minutes
hope this helps
Answer:
Step-by-step explanation:
We know that the mean and standard deviation of the sampling distribution of the sample proportion() is given by :-
, where p= Population proportion and n = sample size.
Let p be the proportion of blue chips.
As per given , we have
p= 0.275
n= 5
Now , the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5 will be :
Hence, the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5 are :
