Sanderson Manufacturing produces ornate, decorative wood frame doors and windows. Each item produced goes through three manufacturing processes: cutting, sanding, and finishing. Each door produced requires 1 hour in cutting, 30 minutes in sanding, and 30 minutes in finishing. Each window requires 30 minutes in cutting, 45 minutes in sanding, and 1 hour in finishing. In the coming week Sanderson has 40 hours of cutting capacity available, 40 hours of sanding capacity, and 60 hours of finishing capacity. Assume all doors produced can be sold for a profit of $500 and all windows can be sold for a profit of $400.Required:a. Formulate an LP model for this problem. b. Sketch the feasible region. c.

Suppose that weekly income of migrant workers doing agricultural labor in Florida has a distribution with a mean of $520 and a standard deviation of $90. A researcher randomly selected a sample of 100 migrant workers. What is the probability that sample mean is less than $500

Answers

Answer:

$z = (500-520)/((90)/(√(100)))= -2.22$

And we can find this probability using the normal standard distribution and we got:

$P(z<-2.22) =0.0132$

Step-by-step explanation:

For this case we have the foolowing parameters given:

$\mu = 520$ represent the mean

$\sigma =90$ represent the standard deviation

$n = 100$ the sample size selected

And for this case since the sample size is large enough (n>30) we can apply the central limit theorem and the distribution for the sample mean would be given by:

$\bar X \sim N(\mu , (\sigma)/(√(n)))$

And we want to find this probability:

$P(\bar X <500)$

We can use the z score formula given by:

$z = (500-520)/((90)/(√(100)))= -2.22$

And we can find this probability using the normal standard distribution and we got:

$P(z<-2.22) =0.0132$
