The quality-control inspector of a production plant will reject a batch of syringes if two or more defective syringes are found in a random sample of nine syringes taken from the batch. Suppose the batch contains 1% defective syringes. (a) Make a histogram showing the probabilities of r = 0, 1, 2, 3, , 8 and 9 defective syringes in a random sample of nine syringes. (b) Find μ. What is the expected number of defective syringes the inspector will find? (c) What is the probability that the batch will be accepted? (d) Find σ. Step 1 (a) Make a histogram showing the probabilities of r = 0, 1, 2, 3, , 8 and 9 defective syringes in a random sample of nine syringes. Recall that the binomial distribution with parameters n, p, and r gives the probability distribution of the number of r successes in a sequence of n trials, each of which yields success with probability p. Here we can let "success" be defined as "finding a defective syringe." The batch contains 1% defective syringes, so there is a 1% chance that any given syringe will be found to be defective. Therefore, p = 0.01 . A random sample of nine syringes are checked for quality, so n = 9

Step 2

We are interested in the probability of r defective syringes when r = 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Use this table to create a table of r values and the corresponding

P(r)

values when n = 9 and p = 0.01. (Round your answers to three decimal places.)

  1. Suppose the firm is currently using 4 units of capital and 4 units of labor. Is the corresponding output being produced at least cost? How do you know?



  2. What combination of labor and capital should the firm use to maximize its profit? Show.



  3. If the marginal product of each resource does not depend on the quantity of the other resource, what output level corresponds to the input combination you just found? Show how.


  4. Does this combination produce this output level at least cost?

Write a method sumTo that accepts an integer parameter n and returns the sum of the first n reciprocals.

In other words: sumTo(n) returns: 1 + 1/2 + 1/3 + 1/4 + ... + 1/n

For example, the call of sumTo(2) should return 1.5. The method should return 0.0 if passed the value 0 and should print an error message and return -1 if passed a value less than 0.

Include a loop.

  1. Find the mean hours of exercise per week by the participant.  
  2. Find the variance and standard deviation of the hours of exercise per week by the participants.
  3. Run a bivariate correlation to determine if there is a linear relationship between the hours of exercise per week and the life satisfaction. Report the results of the test statistic using correct APA formatting.
  4. Run a linear regression on the data. Report the results, using correct APA formatting. Identify the amount of variation in the life satisfaction ranking that is due to the relationship between the hours of exercise per week and the life satisfaction (Hint: the R2 value)
  5. Report a model of the linear relationship between the two variables using the regression line formula.
