Question 1074987
The first is 95%, because 734 and 1086 are -2 sd and +2 sd from mean.  
Find 36% is not clear.  If it means where is the middle 36%, one looks in the table at 0.32 and 0.68, which is the middle 36% and finds z=-0.47 and z=+0.47
multiply 0.47*88 to get 41.36 or 41.4 
Add and subtract that to the mean to get (868.6, 951.4).
------------------
Empirical rule for 99.7% is +/- 3 sd or +/-264
(646, 1174)
-----------------------------
Chebyshev's for +/-2 sd at least 3/4 (1-1/sd^2; 1-1/4) or 75%.
For the next one 36% is 1-0.64 where 0.64 is 1/x^2, where x= # sd s.
x^2=1/0.64
x=1/0.8=1.25 sd s
This is 88*1.25 or 110
(800, 1020)

c I answered above.
---------------
d is 95% as outlined above.
