<u>Answer:</u>
Nadia's total earnings in month is $3196.1
<u>Explanation: </u>
Given salary of Nadia is $3,300 per month including a 3.25% commission
The salary consists of fixed salary and commission
Therefore, Salary = Fixed salary + Commission
Assume the fixed salary to be x
Putting values in equation
3300 = x + 3.25% of x
3300 = x +
3300 * 100 = 103.25x
x =
x = $3196.1 per month
Therefore, the fixed salary of Nadia is $3196.1 per month
Answer:
The standard deviation of the sample mean is 4 minutes
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
The standard deviation of the population is 32.
Sample of 64.
So
The standard deviation of the sample mean is 4 minutes
