Cafe Espresso is a very popular coffee shop at UCI. The owner of Cafe Espresso notices that on average85 customers order coffee on a given day. Let X be the number of customers who order coffee at CafeEspresso, and we will assume that E[X] = 85.(a) Assume that the expected value of X is a constant daily rate and the number of customers whoorder coffee at Cafe Espresso is independent of any other day. What is the distribution of X?Justify your answer.(b) Using the distribution from part (a), what is the Mean and Standard Deviation of the number ofcustomers who order coffee at cafe express in a give day.(c) Using the distributing from part (a), what is the probability that at least 81 customers order coffeeat Cafe Espresso in a given day?(d) Suppose that the number of costumers who order coffee at Cafe Espresso in any increment of timeis independent of the number of costumer who order coffee at Cafe Espresso in any other incrementof time. Suppose that Cafe Espresso only opens between 6:00am and 3:00pm. 1) What is theprobability that at least 11 costumer order coffee in one hour during a given day? 2) What is theprobability that no costumer order coffee in one hour during a given day?(e) Using the assumption from above, what is the expected number of customers who order coffee atCafe Espresso in one quarter? Assume that each day is independent of the other days and thatthere are 70 days in a quarter.

Let qty denote quantity demanded, price denote price, and suppose we estimate the model log(qty) = ß1 + B2 log(price)+ e where E[e| log(price)] = 0 and we assume e is homoscedastic so Var(e| log(price)) = o². In the data, we find E- log(price,) = 0, b1 = 2.5, b2 = 0.9, Var (bj) = 1, and Var (b2) = 0.1. Suppose we are interested in estimating a = B1 + 10B2 and for this end we use the estimator å1 = b1 + 10b2. What is your estimate for the variance of A? (Usually denoted by Var (Â)) O a.

A population of fish is living in an environment with limited resources. This environment can only support the population if it contains no more than M fish (otherwise some fish would starve due to an inadequate supply of food, etc.). There is considerable evidence to support the theory that, for some fish species, there is a minimum population m such that the species will become extinct if the size of the population falls below m. Such a population can be modelled using a modified logistic equation: dP =(1-)(-) m dt M
A toll bridge charges $1.00 for passenger cars and $2.75 for other vehicles. Suppose that during daytime hours, 65% of all vehicles are passenger cars. If 20 vehicles cross the bridge during a particular daytime period, what is the resulting expected toll revenue? [Hint: Let X = the number of passenger cars; then the toll revenue h(X) is a linear function of X.]
A researcher is interested in finding out how the past average daily values of the stock prices of a firm A determine the current average daily value of its stock price. Let pt ( measured in dollars) denote the average daily value of the stock price of firm A at time t. The researcher collects data on the average daily values of the stock prices of the last quarter of 2017, i.e., t = 1,2, dots,90 and estimates the following autoregressive model with 1 lag of pt: hat(p)t = 2.48 +.05pt.1bar (R)² = 0.512, SER = 13.14. (1.13) (0.64) The standard errors are given in parentheses. Suppose that the actual average daily value of the stock price on January 2, 2018 was $506.12 and the average daily value of the stock price on December 31, 2017 was $445.12. The forecast error in the estimation of the average daily value of the stock price on January 2, 2018 will be $ (Round your answer to two decimal places.) This is all the info in the question

A study done in 1994, of Maryland's portion of Chesapeake Bay found the following information about stocks of market-sized oysters. The stock population was 218 million, the stock will not exceed 5089 million oysters, and the intrinsic exponential growth rate is 0.274 per year.
A problem that occurs with certain types of mining is that some byproducts tend to be mildlyradioactive, and these products sometimes get into our freshwater supply. The EPA has issuedregulations concerning a limit on the amount of radioactivity in supplies of drinking water.Particularly, the maximum level for naturally occurring radiation is 5 picocuries per liter ofwater (on average). A random sample of 24 water specimens from a city’s water supply gave ̄x= 4.61 and s = 0.87. Do these data provide sufficient evidence to indicate that the meanlevel of radiation is safe (below the maximum level set by the EPA)? Test usingα= 0.05.
