Workers at a large toxic clean up project are concerned that their white blood cell counts may have been reduced. Let x be a random variable that represents white blood cell count per cubic millimeter of whole blood in a healthy adult. Then m= 7500 and o= 1750. A random sample of n=50 workers from the toxic cleanup site were given a blood test that showed x= 6820. What is the probability that, for healthy adults, x will be this low or lower?
The area under a normal curve is always equal to 1, no matter what the mean and standard deviation are.
Suppose B^0 and B^1(beta hut 0 and beta hut 1) are the least squares estimates of B0 and B1 of the first model. Find the estimates of B0* and B1* in terms of B^0 and B^1.
A normal population has a mean of 75 and a standard deviation of 5. You select a sample of 40. Compute the probability that the sample mean is Between 74 and 76.
The summation sign is usually represented by:
Indicate which of the following responses below is correct. Discuss why it is correct or discuss why standard deviation is such a valuable statistic in so many situations.
Many educators feel their grades should fit a normal distribution and often apply curves to make them fit one. One way to do this is to convert numeric grades to z scores using the mean and standard deviation for the grades, then use an equation s..
Regression model results can be erroneous if multicollinearity is an issue. What causes multicollinearity? If the intercept is statistically significant, what does this tell you?
The firm has already decided that any sample mean below 78 or above 82 will signal the workers that the process is not working properly.
Write complete linear programming model (All three parts) to find out the number of items to be transported from models A, B, C, and D to nodes 1 and 2 at minimum cost.
Choose a variable and collect data for a least three different groups(samples). Compare the means of the three groups using the one-way ANOVA technique. Complete the following:
Suppose the waiting time at a restaurant is normally distributed with a mean of 12 minutes and a standard deviation of 6 minutes.
