Consider a manufacturing process that produces cylindrical component parts for the automotive industry. According to specifications, it is important that the process produces parts having a mean diameter of 5.0 millimeters. An experiment is conducted in which 100 parts produced by the process are selected randomly and the diameter measured on each part. It is known that the population standard deviation is 0.1. It was found that the sample mean diameter is 5.027 millimeters. The process engineer Mr. Tan would like to find out how likely is it that one could obtain a sample mean diameter of at least 5.027 with sample size n = 100, if the population mean µ = 5.0. Apply the concept of central limit theorem. Mr Tan claimed that “In only 7 in 1000 experiments, one would experience by chance a sample mean that deviates from the population mean by as much as 0.027.” Do you agree? Explain your reasoning.

M3 Discussion: The Respiratory System
This is something of a different type of discussion. Discuss in 1-2 short paragraphs 2 of the most informative pieces of information you learned in this chapter. You can discuss one of the homeostatic imbalances, a fundamental principle of respiratory capacities, gas exchange, etc, anything that was presented in the chapter you particuarly are interested in.

Two firms, A and B, sell widgets to a market of 100 buyers. The firms' widgets are undifferentiated, and the firms know each others' costs and capacities. Furthermore the firms are playing a one-time pricing game; widgets are obsolete after this one selling opportunity. Each buyer is interested in purchasing a single widget, and has an RP of $10.
Firm A has lower costs than Firm B, but also has lower capacity. Specifically, their (constant) marginal costs and capacities are as follows.
|
Marginal Cost |
Capacity |
|
|
Firm A |
5 |
30 |
|
Firm B |
7.1 |
100 |
Finally, assume that each firm can only post prices in whole dollar amounts. (This question is motivated by firms selling through coin-operated vending machines. It is too costly to stock such machines with pennies, so sellers must set prices in fixed increments of larger denomination coins.) Throughout this entire problem, firms may only choose prices of $1.00, $2.00, $3.00, ..., up to $10.00. Firms may NOT use prices such as $1.50, $2.99, $3.83, etc.
(2a.) Find equilibrium prices for this one-time pricing game. (As usual: all buyers go to the firm with the lowest price. However if Firm A's price is no higher than Firm B's price, Firm A serves only 30 buyers, and the rest go to Firm B. Your answer should be a pair of prices, one for each firm.)
(2b.) Suppose that before the pricing game starts, Firm A can build a production plant that would have full capacity of 100 units. (Marginal costs would remain the same, and Firm B would see Firm A's new capacity. Then firms would simultaneously set some equilibrium prices.)
Ignoring the cost of building, how much profit would Firm A earn if it expanded? Firm A would now earn profits of ______________. (You must show your calculations for credit. The same assumptions apply as the previous part, except now the firms split the market 50/50 if they price equally.)

It takes two materials to produce our widgets, Material X and Material Y. All of Material X is added at the beginning of processing, and all of Material Y is added at the 30% point in processing. At the beginning of March, there were 8000 units in Work in Process, 20% complete as to processing (Conversion). During March, there were 30000 units started into the process. At the end of March, there were 5000 units in Work in Process, 70% complete as to processing, Our Company uses the FIFO method of process costing. Prepare an equivalent units chart for the month of March
In April, we started 40000 units and completed 39000 units. The ending Work in process for April was 10% complete as to processing. Prepare an equivalent units chart for April.

Okay for this question, I obviously don't need a quantity because I dont have any, but how would I approach this question in lab if asked:
