Answer:
Hello,
answer is 204 in base 10 or 21120 in base 3
Step-by-step explanation:

Answer:
a) 
b) Null hypothesis: 
Alternative hypothesis: 
And we can use a t test procedure in order to check if the true mean is equat to the desired value.
Step-by-step explanation:
For this case we know that this:
Claim: The mean pulse rate (in beats per minute) of adult males is equal to 69.5 bpm
Part a
If we convert this with symbols we can write this as:

Part b
We have the following info given:
represent the sample mean
represent the sample size
We have the following system of hypothesis:
Null hypothesis: 
Alternative hypothesis: 
And we can use a t test procedure in order to check if the true mean is equat to the desired value.
The order will be 1/6 2/5 3/7 3/5
The Mean Absolute Deviation is - 0 +0+0+1+3+8 = 24/ 6 which would = 4 that's the answer to your question .
Hope that it helps .
