X-7=0 X+7=0
X=7 X=-7
The z score for a per - day expense of $400 is 0.65 while about 84.13% of the hotels is greater than $268
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
a) For an expense of $400:
The z score for a per - day expense of $400 is 0.65
b) For an expense greater than $268:
P(x > 268) = P(z > -1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413 = 84.13%
About 84.13% of the hotels is greater than $268
