Answer: 160.4040
Step-by-step explanation:
Here , the claim is "The standard deviation of pulse rates of adult males is more than 11 bpm." , i.e. 
We use Chi-square test statistic for the test statistic to test the standard deviations :
, where s= sample standard deviation , 
= population standard deviations and n = sample size.
As per given , n=153 , s= 11.3
Then, Required test statistic will be :
Hence, the value of the test statistic. = 160.4040
The Pythagorean theorem is helpful here.
.. x^2 +20^2 = 50^2
.. x^2 = 2500 -400 = 2100
.. x = 10√21 ≈ 46 . . . . feet
