The time between arrivals of taxis at a busy intersection is exponentially distributed with a mean of 10 minutes. (ii) Suppose that you have already been waiting for one hour for a taxi. What is the probability that one arrives within the next 10 minutes? (iii) Determine x such that the probability that you wait more than x minutes is 0.10. (iv) Determine x such that the probability that you wait less than x minutes is 0.90.

Suppose that the amount of service(ordering a coffee and getting it done) time at a KU driving- through coffee shop is exponentially distributed with an expected value of 10 minutes. You arrive at the driving-through line while one customer is being served and one other customer is waiting in the line. The staff of the coffee shop informs you that the customer has already ordered a Cafe Latte and waited for 5 minutes. What is the probability that the customer...

Suppose d machines are subject to failures and repairs. The failure times are exponentially distributed with parameter μ, and the repair times are exponentially distributed with parameter λ. Let x(t) denote the number of machines that are in satisfactory order at time t. If there is only one repairman, then under appropriate reasonable assumptions, X(t), t 2 0, is a birth and death process on {O, 1,..., d} with birth rates λχ-λ, 0 x < d, and death rates μΧ_xp,...

1. Suppose you are using a = 0.05 to test the claim that > 13 using a P-value. You are given the sample statistics n = 35, x = 13.3, and s-1.2. Find the P-value. The p-value is 2. In the test above, what is the standardized test statistic? The standardized test statistic: t = or z = (circle one and fill in) 3. Given He: p 2 80% and H. p < 80%, determine whether the hypothesis test is...

The time between arrivals of taxis is exponentially distributed with a mean of 10 minutes. a) You are fourth in line looking for a taxi. What is the probability that exactly 3 taxis arrive within one hour? b) Suppose the other three parties just decided to take the subway and you are now the first in line for the next taxi. Determine the time t such that the probability you wait less than t minutes from now until the next...

1. Suppose that you are testing the following hypotheses: ?0: ? = 10 and ?1: ? > 10. If the null hypothesis is rejected at the 1% level of significance, what statement can you make about the confidence interval on the mean? a.) The lower bound of a 95% one-sided confidence interval on the mean exceeds 10 b.) 9 ≤ ? ≤ 13 c.) No statement can be made d.) The lower bound of a 95% one-sided confidence interval on...

Suppose that textbook weights are normally distributed. You measure 21 textbooks' weights, and find they have a mean weight of 75 ounces. Assume the population standard deviation is 11.4 ounces. Based on this, construct a 95% confidence interval for the true population mean textbook weight. Round answers to 2 decimal places.

2. You have isolated a protein from sperm that you suspect is involved in binding to the zona pellucida and triggering the acrosome reaction. You generate an antibody to this protein and use the antibody to isolate the protein. You have obtained peptide information and used this peptide data to identify the DNA sequence that encodes your protein of interest. a. What zona protein do you suspect this sperm protein binds to? b. What expression pattern is consistent with your...
