Question

The average hourly wage of workers at a fast food restaurant is $8.50/hr. Assume the wages are normally distributed with a standard deviation of $0.40. If a worker at this fast food restaurant is selected at random, what is the probability that the worker earns more than $9.25? Write your answer as a percentage and round to two decimal places.

Answer #1

The average hourly wage of workers at a fast food restaurant is
$6.50/hr. Assume the wages are normally distributed with a standard
deviation of $0.45. If a worker at this fast food restaurant is
selected at random,
What is the probability that the worker earns more than
$6.75?
What is the probability that the worker earns between $6.50 and
$6.75?

The average hourly wage of workers at a fast food restaurant is
$7.50/hr with a standard deviation of $0.75. Assume that the
distribution is normally distributed. If a worker at this fast food
restaurant is selected at random, what is the probability that the
worker earns between $7.50 and $8.25?

The hourly wage for workers in a fast food restaurant is
Normally distributed with a mean of $5.85 and a standard deviation
of $0.35. If a worker is selected at random, find the probability
that:
a. (S)he earns less than $5.50 an hour
b. (S)he earns between $5.90 and $6.40 an
hour
c. (S)he earns at least $6.00 an hour

For certain workers, the mean wage is $6.50/hr, with a
standard deviation of $0.25 If a worker is chosen at random, what
is the probability that the worker's wage is between $6.25 and
$6.75? Assume a normal distribution of wages.
The probability is _____.

A company pays its employees an average wage of $3.25/hour with
a standard deviation of $0.60. If the wages are
approximately normally distributed,
determine: [5x4=20pts]
…graph a normal curve in all 4 parts.
The probability that randomly chosen worker has the hourly wage
less than $3.

a union of restaurant and food service workers would
like to estimate this year's mean hourly wage meu for Food Service
workers in the US. last year's meu hourly wage was $8.16 and there
is reason to believe that this year's value is greater than last
year's. the Union decides to do a statistical test to see if it can
be concluded that the men has increased. the union choose a random
sample of 50 wages from this year. suppose...
