A waitress believes the distribution of her tips has a model that is slightly skewed to the left, with a mean of $8.30 and a s

kondaur [170]

Answer:

probability = 0.9286

Step-by-step explanation:

given data

mean = $8.30

standard deviation = $4.70

waits parties over a weekend of work = 60

solution

when we earn at least $550 in 60 parties

so average per party will be x = $\frac{550}{60}$

average x = 9.1667

so now we get here z value that is

$z = \frac{x-\mu }{\sigma }$ ...............1

put here value and we get

z = $\frac{9.1667-8.30}{4.70}$

z = 0.184404

P(x>9.1667) = P(z>0.184404)

use standard normal table

probability = 1 - 0.0714 = 0.9286
