Question: A robot is given 1 random instruction every second for 10 seconds. Each

instruction will be either a command to move 1 inch to the left, or 1 inch

to the right. The likelihoods of the instruction being a command to move

to the left and right are 'p' and '1-p', respectively.

Find:

a) What is the expectation of the robot's final position with respect

to its starting position.

b) What is the variance we might expect for observations of the

robot's final position?

c) For what value(s) of 'p' is this variance greatest?

d) For what value(s) of 'p' is the expectation of net distance traveled greatest?

e) For what value(s) of 'p' is the total number of inches moved greatest?

1. A random sample of 64 second graders in a certain school district are given a standardized mathematics skills test. The sample mean score is 51.58. Assume the standard deviation for the population of test scores is 15. The nationwide average score on this test us 50. The school superintendent wants to know whether the second graders in her school district have greater math skills than the nationwide average. Perform the hypothesis test and compute the P value. Based on...

A "seconds" pendulum is one that goes through its equilibrium position once each second. (The period of the pendulum is 2.000 s.) The length of a seconds pendulum is 0.9927 m at Tokyo and 0.9942 m at Cambridge, England. What is the ratio of the free-fall accelerations at these two locations? (Give your answer to at least 4 decimal places.) Cambridge /Tokyo =

Assume that for a given program 70% of the executed instruction are arithmetic, 10% are load/store, and 20% are branch. i. Given the instruction mix and the assumption that an arithmetic instruction requires 2 cycles, a load/store instruction takes 6 cycles, and a branch instruction takes 3 cycles, ?nd the average CPI. ii. For a 25% improvement in performance, how many cycles, on average, may an arithmetic instruction take if load/store and branch instructions are not improved at all.

1. Every two seconds someone in America needs blood. It is important that hospitals have the right types of quality blood to meet the patient needs. Blood donation centers help hospitals meet this demand. There are four main blood groups: A, B, AB, and O, of which O is the most common. One of the less common blood types is B+. In the United States, only 9% of the population has B+ blood type. Assume that 5 donors arrive to...

Question 1. For each random variable, state whether the random variable should be modeled with a Binomial distribution or a Poisson distribution. Explain your reasoning. State the parameter values that describe the distribution and give the probability mass function. Random Variable 1. A quality measurement for cabinet manufacturers is whether a drawer slides open and shut easily. Historically, 2% of drawers fail the easy slide test. A manufacturer samples 10 drawers from a batch. Assuming the chance of failure is...

Consider a one-dimensional random walker (using numpy) that can move every second. With probability pl = 1/3 it moves to the left, with probability pr = 1/3 it moves to right, and with probability pr = 1/3 it rests and does not move. Assuming at time t = 0, the random walker is at x = 0, plot (using matplotlib) the probability density function and the cumulative probability function for t = 10, t = 100, and t = 1000...
