Balance in account cannot be less than
Answer:
3 hours 40 minutes.
Step-by-step explanation:
We are told that we have 1320 garments and it takes an employee 20 seconds to tag a garment.
1 employee tags one garment in 20 seconds.
So garments tagged by 1 employees in 1 minute will be garments.
2 employees will tag 3*2=6 garments in 1 minute.
To find the total time it will take two employees to tag all the garments we will divide total number of garments by 6.
Therefore, it will take 220 minutes or 3 hours and 40 minutes for 2 employees to tag 1320 garments.

As described in z-distribution the answers are given below:
a) The 95% confidence interval estimate for the population mean spending by a customer on visiting salon per month is given as follows: (747, 853).
b) The sampling error at 95% confidence level is of: $35.78.
What is a z-distribution ?
The normal distribution with a mean of 0 and a standard deviation of 1 is referred to as the standard normal distribution (also known as the Z distribution) (the green curves in the plots to the right). It is frequently referred to as the bell curve since the probability density graph resembles a bell.
solution:
The bounds of the confidence interval are given as follows:
In which:
is the sample mean.
z is the critical value.
n is the sample size. is the standard deviation for the population.
The parameters for this problem are given as follows:
Hence the lower bound of the interval is of:
800 - 200 x 1.96/square root of 55 = 747.
The upper bound of the interval is of:
800 + 200 x 1.96/square root of 55 = 853.
The sampling error for a sample size of 120 is calculated as follows:
200 x 1.96/square root of 120 = $35.78.
