Answer:
0.0579 is the probability that mean systolic blood pressure is between 119 and 122 mm Hg for the sample.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 114.8 mm Hg
Standard Deviation, σ = 13.1 mm Hg
Sample size = 23
We are given that the distribution of systolic blood pressures is a bell shaped distribution that is a normal distribution.
Formula:

Standard error due to sampling:

P(blood pressure is between 119 and 122 mm Hg)
 

0.0579 is the probability that mean systolic blood pressure is between 119 and 122 mm Hg for the sample.

Based on a quick internet search.
        
             
        
        
        
87,602 in expanded form is 80,000+7,000+600+2
 
        
                    
             
        
        
        
So in 1 hour, the parachutist will fall 12 miles or
12 mi/1hour
convert
1 hour=60 mins
1 min=60 seconds
1 hour=60 times 60 seconds=360 seconds
12 miles per 360 seconds
convert miles to feet
5280 feet per mile
12 miles times 5280=63360 feet
63360/360
do the math and simplify
63360/360=6336/36=176
176 feet per second
