(CO 1) In a normally distributed data set of how long customers stay in your store, the mean is 31.7 minutes and the standard deviation is 1.9 minutes. Within what range would you expect 95% of your customers to stay in your store
Answers
Answer:
The range is between 27.9 minutes and 35.5 minutes.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 31.7 minutes
Standard deviation = 1.9 minutes.
Within what range would you expect 95% of your customers to stay in your store
Within 2 standard deviations of the mean.
Lower bound: 31.7 - 2*1.9 = 27.9 minutes
Upper bound: 31.7 + 2*1.9 = 35.5 minutes
The range is between 27.9 minutes and 35.5 minutes.

A quality control expert at Glotech computers wants to test their new monitors. The production manager claims they have a mean life of 75 months with a standard deviation of 5 months. If the claim is true, what is the probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
Answers
Answer:
86.65% probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question:
Population: [tex]\mu = 75, \sigma = 5[/tex]
Sample of 85: [tex]n = 85, s = \frac{5}{\sqrt{85}} = 0.5423[/tex]
If the claim is true, what is the probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
This is 1 subtracted by the pvalue of Z when X = 74.4. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{74.4 - 75}{0.5423}[/tex]
[tex]Z = -1.11[/tex]
[tex]Z = -1.11[/tex] has a pvalue of 0.1335
1 - 0.1335 = 0.8665
86.65% probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors

Admission to a museum is $7.10 per
adult and $4.80 per child. The expression
7.1a 1 4.8c represents the total cost in
dollars for admission for a adults and
c children.
If 6 adults and 6 children attend the
museum, what is the total cost?
Answers
The total cost of admission for 6 adults and 6 children to the museum is $71.4.
What is the total cost?Total cost refers to the sum of all costs incurred in producing a product, delivering a service, or achieving a particular outcome. It encompasses all the expenses, both direct and indirect, that are associated with a specific activity, project, or process.
According to the given information:
To calculate the total cost of admission for 6 adults and 6 children to the museum, we can substitute the values of "a" and "c" into the given expression "7.1a + 4.8c" and perform the calculations.
Given:
Number of adults (a) = 6
Number of children (c) = 6
Admission cost per adult = $7.10
Admission cost per child = $4.80
Substituting the values into the expression:
7.1a + 4.8c = 7.1 * 6 + 4.8 * 6
Now, we can perform the calculations:
7.1 * 6 = 42.6
4.8 * 6 = 28.8
Adding the results together:
42.6 + 28.8 = 71.4
So, the total cost of admission for 6 adults and 6 children to the museum is $71.4.

Step-by-step explanation:
Hi there!
First you separate your expression into groups.
[tex](y^2-5y)(-1y+5)[/tex]
Now we take the common multiple out of each.
[tex]y(y - 5)-1(y - 5)[/tex]
Since we have two (y - 5)s, we can pull it out of the equation as its own common multiple.
After we do that, we are left with y - 1. (we got this from taking the common multiples out)
Now we are just left with (y - 5)(y - 1)
