A player is randomly dealt a sequence of 13 cards from a deck of 52-cards. All sequences of 13 cards are equally likely. In an equivalent model, the cards are chosen and dealt one at a time. When choosing a card, the dealer is equally likely to pick any of the cards that remain in the deck. What is the probability the 13th card dealt is a King?

5. True or False. (a) All other factors remaining the same, increasing the sample size, n, will decrease the width of a con dence interval. (b) We expect 95% of all 95% con dence intervals for the population mean to contain the sample mean. (c) The t-distribution is symmetric and centered at the population mean . (d) The t-distribution is very similar to the standard normal distribution regardless of its degrees of freedom. (e) All other factors remaining the same, a 90% con dence interval for a population mean is narrower than an 95% con dence interval for the same . 1

Which of the following statements will always hold true? It will never be appropriate for a rapidly growing startup company that pays no dividends at present—but is expected to pay dividends at some point in the future—to use the constant growth valuation formula. The constant growth valuation formula is not appropriate to use unless the company’s growth rate is expected to remain constant in the future. The constant growth valuation formula is not appropriate to use for zero growth stocks

Over the past several years, the owner of a boutique on Aspen Avenue has observed a pattern in the amount of revenue for the store. The revenue reaches a maximum of about $ 59000 in April and a minimum of about $ 29000 in October. Suppose the months are numbered 1 through 12, and write a function of the form f(x)=Asin(B[x−C])+D that models the boutique's revenue during the year, where x corresponds to the month. If needed, you can enter π=3.1416... as 'pi' in your answer.

Diffusion and Solubility of Gases (B. Flaconn'eche, et al., Oil and Gas Science and Technology, 2001:262-278) reported on a study of the effect of temperature and other factors on gas transport coefficients in semi crystalline polymers. The permeability coefficient (in 10-6 cm3 (STP)/cm. s. MPa) of CO2 was measured for extruded medium density polyethylene at both 60 degree C and 61 degree C. The results are as follows: 60⁰ C54516167576960606362 61⁰ C58606666686160 (1) Find Mean of 60 degree sample to nearest 0.1 (2) Find mean of 61 degree sample to nearest 0.1 (3) Find sample standard deviation of 60 degree sample to nearest 0.01 (4) Find Sample standard deviation of 61 degree sample to nearest 0.01 (5) What are the degrees of freedom? (6) Center of Confidence interval? (7) Width of confidence interval (remember to multiply by 2?) (8) If everything was the same except that we had one more sample in each group, would the above confidence interval get longer or shorter or stay the same?
