One wants to study the daily mean travel distance of a delivery service. In trial runs of 18 randomly chosen delivery trucks, the mean and the standard deviation are found to be 310 km and 70km, respectively. Assume that the daily travel distance is normally distributed. At the 0.1 level of significance, test the claim that the daily mean travel distance is different from 350 km. What is the CONCLUSION?

Select one:

a. there is not enough assumptions to do a hypothesis test in this case.

b. None of the other answers is true.

c. there is sufficient sample evidence to support the claim that the daily mean travel distance is more than 350 km.

d. there is insufficient sample evidence to support the claim that the daily mean travel distance is different from 350 km.

e. there is sufficient sample evidence to support the claim that the daily mean travel distance is equal to 350 km.

Susan runs a store that sells furniture. One day, Brittney, a customer, walks in the store. After looking around the store, Brittney approaches Susan to buy an expensive wooden chair for $1,200. Susan gives Brittney a written contract for the purchase of the chair, which Brittney reads. While Brittney is reading the contract, Susan tells Brittney, “If you sign now, we can also deliver to you a free luxury wooden table to go with the chair.” Brittney tells Sarah, “Oh that would be perfect,” and signs the written contract for the purchase of the chair. A week later, Brittney receives the chair by delivery, but not the table. Upset, Brittney goes back to the store to confront Susan. Susan tells Brittney that, “Sorry, we ran out of luxury tables. And our written contract only mentions the luxury chair which we have delivered, and the $1,200 which you have paid.” Susan refuses to give Brittney the luxury table. Advise Brittney if she can enforce Susan’s oral promise to give Brittney the luxury table. Please only use the material in Contracts 2 to answer the question. Do NOT discuss terms and representations and/or conditions or warranties in your answer.

Please also note: a written contract, has been formed. USE ILAC METHOD

Normal distribution. We expect an LED light bulb to last nine years with a standard deviation of two years. It follows a normal distribution. Find the probability that a light bulb will last between five and seven years.

You own one call option and one put option on Shell, both with a strike price of 80. The interest rate is 5% and the time to expiration is nine months. The standard deviation of Shell is 25 percent. Graph on the same graph the value of the call and the put as the price of Shell goes from 70 to 130. (So that is two lines on the same graph.) Note:at least 50 data points on the graphs

Suppose you have 4 factors to investigate. You have resource to do 2 replicates of a 2^4 design. But you can only conduct 8 runs every day. How would you set up the treatments for each day? What will be the degree of freedom for MSE in your ANOVA table?

A backpacker weighs 180 pounds. Assume his blood weight is about 7% of his body weight. His hematocrit at rest is 40%, and his total plasma proteins 6 g%. After hiking on a hot day, the backpacker loses a net 4 L of body fluid by sweating and drinking, where the drinking is insufficient to match his sweating. Assume that the plasma makes up 8% of his total body water and that the fluid lost from each compartment is in proportion to the size of each fluid compartment.

(A) Assuming no loss of blood, what is his hematocrit after his hot hike?

(B) What is his total plasma protein concentration after hiking?

(C) What effect would these changes have on his blood viscosity?

(D) Describe how the body reacts to losing water due to sweat, and to taking too much water from a meal. In general, how is the water balance reached?
