Suppose that TCP's current estimated values for the round-trip time (estimatedRTT) and deviation in the RTT (DevRTT) are 100 msec and 20 msec, respectively. Suppose that the next ONE measured values of the RTT are 500 msec.

Compute TCP's new value of DevRTT, estimatedRTT, and the TCP timeout value after ONE measured RTT values is obtained. Use the values of α = 0.125, and β = 0.25.

You are considering Project B that requires an initial investment of $70. The current present value of its cash flows is estimated to be $100 based on today’s market conditions. You can undertake Project B now or wait for one month to decide. The current risk-free rate is 0.25%, and the standard deviation of project return is 10%. What should you do? Suppose instead that the initial investment for Project B is $100, the current present value of its cash...

Our study shows that one customer will have different transaction values in the next five years with Giant Tiger (See Table 6). The gross contribution is 0.25 and discount rate is 0.01. Suppose current year is 2006. Please figure out the Lifetime Value (LTV) of this customer. Suppose we have total 2000 customers who will share the same purchase patterns as this customer in the next five years. How much is the customer equity? Table 6.

Question: Suppose you have been hired by a research firm trying to understand the market for Widgets (a hypothetical product). Your analysis of the data indicates that the Demand curve for Widgets is estimated to be linear and given by equation Qd = 100 – P and the Supply curve for Widgets appears to be linear as well and is estimated as Qs = 3P – 20. Graphically draw these two curves, labeling all relevant points (such as intercepts for...

Suppose that the manager of a company has estimated the probability of a super-event sometime during the next three years that will disrupt all suppliers as 2%. In addition, the firm currently uses four suppliers for its main component, and the manager estimates the probability of a unique-event that would disrupt one of them sometime during the next three years to be 20%. Supplier management costs during this period are $50,000 per supplier. The financial cost incurred if all four...

Suppose a company manufactures ropes that are known to, on average, break when sup- porting 75kg. An engineer claims that her ropes are superior (have a higher break point), but they also cost substantially more to manufacture. In the context of a hypothesis test, we would make the following assumption about the new rope Ho: μ = 75 and look for evidence of her claim Ha : μ > 75. Let’s assume σ is known to be 9 for the...

The Student's t distribution table gives critical values for the Student's t distribution. Use an appropriate d.f. as the row header. For a right-tailed test, the column header is the value of α found in the one-tail area row. For a left-tailed test, the column header is the value of α found in the one-tail area row, but you must change the sign of the critical value t to −t. For a two-tailed test, the column header is the value...

A simple random sample of 100 postal employees is used to test if the average time postal employees have worked for the postal service has changed from the value of 7.5 years recorded 20 years ago. The sample mean was x¯ = 7 years with a standard deviation of s = 2 years. Assume the distribution of the time the employees have worked for the postal service is approximately Normal. The hypotheses being tested are H0 : µ = 7.5,...

Suppose that you wish to invest in two stocks which both have a current price of $1. The values of these two stocks in one month are described by two random variables, say, X1 and X2. Suppose that the expected values and standard deviation of X1 and X2 are μ1, μ2, σ1 and σ2, respectively. We also assume that the correlation between the stocks is given by ρ. Let c denote your initial investment, which is to be invested in...
