1:The weights of packets of cookies produced by a manufacturer have a normal distribution with mean 202 grams and standard deviation 3 grams. What is the weight that should be written on the packet so that only 1 percent is underweight?
2:A company receives a very large shipment of components. A random sample of sixteen of these components is checked, and the shipment is accepted if fewer than two of the sampled components are defective. What is the probability of accepting a shipment containing 25% defectives?
3: You are interested in the proportion of smokers. Consider a population consisting of N = 4 elements: the first two persons smoke, while the remaining two do not smoke. That is {S, S, N, N}
(a) In this population, what is the proportion of smokers?
(b) You take a random sample of size n = 2. How many different random samples are possible?
(c) Write down the sampling distribution of P, the sample proportion of smokers in a random sample of size n = 2 from this population. That is, list the possible outcomes (sample proportions of smokers) and the associated probabilities.
(d) Calculate the mean of the sampling distribution.
Explain the ph probe was miscalibrated and reports the ph
: If the pH probe was miscalibrated and reports the pH and reports the pH to be 1 unit higher than the true pH of the solution it is in, would the molar mass you report for the solid acid be higher than

Find the backward sloping when the wage is given per hour
: Sarah is awake for 100 hours per week. Using one diagram, show Sarah's budget constraints if she earns $6 per hour, $8 per hour, and $10 per hour. Now draw indifference curves such that Sarah's labor supply curve is upward sloping
