12.c 97.64 ................................l.
Answer:
95.44%
Step-by-step explanation:
Mean rate (μ) = 160 euros
Standard deviation (σ) = 8 euros
For any given rate, X, the z-score is:
For X = 144 euros:
For X= 176 euros
In a standard distribution, a z-score of -2 corresponds to the 2.28th percentile, while a z-score of 2 corresponds to the 97.72th percentile.
Therefore, the percentage of hotels with rates between 144 and 176 euros is:
1/10 of 32 million is 3.2 million.
Because
1/10 x 32,000,000 = 3,200,000
