Answer: 2.46
Step-by-step explanation:
Formula for x-score is given by :-

, where
= Sample mean ,
= population mean,
= population standard deviation, n= sample size.
As per given , n=10
= $29,056
= $3,339
= $31,650
Then,

Hence, the z-score = 2.46
25% of something is 5000000, so total is 4*5000000 = 20 million
