Question 4

Researchers studied four different blends of gasoline to determine their effect on miles per gallon (MPG) of a car. An experiment was conducted with a total of 28 cars of the same type, model, and engine size, with 7 cars randomly assigned to each treatment group. The gasoline blends are referred to as A,B,C, and D.The MPGs are shown below in the table

Gasoline Miles Per

Blend Gallon

A 26 28 29 23 24 25 26

B 27 29 31 32 25 24 28

C 29 31 32 34 24 28 27

D 30 31 37 38 36 35 29

We want to test the null hypothesis that the four treatment groups have the same mean MPG vs. the alternative hypothesis that not all of the means are equal.

a) Before carrying out the analysis, check the validity of any assumptions necessary for the analysis you will be doing. Write a brief statement of your findings

b) Test the null hypothesis that the four gasoline blends have the same mean MPGs, i.e., Test Ho: ua=ub=uc=ud vs. the alternative hypothesis Ha: not all the means are equal.

c) If your hypothesis test in (b) indicates a significant difference among the treatment groups, conduct pairwise multiple comparison tests on the treatment group means. Underline groups of homogeneous means.

d) Briefly state your conclusions.

1. Write a standalone function partyVolume() that takes accepts one argument, a string containing the name of a file. The objective of the function is to determine the a Volume object that is the result of many people at a party turning the Volume up and down. More specifically: the first line of the file is a number that indicates the initial value of a Volume object. The remaining lines consist of a single character followed by a space followed by a number. The character will be one of ‘U” or ‘D’ which stand for “up” and “down” respectively. The function will create a new Volume object and then process each line of the file by calling the appropriate method of the Volume object which changes the value of the Volume. The function then returns the final Volume object.   Guidelines/hints:
   1. This is a standalone function, it should NOT be inside (indented within) the class. It should be listed in the module after the Volume class and without indentation.
   2. Note that the first line of the file will be treated differently than all the other lines. Probably the easiest way to do this is to 1) open the file, 2) call the .readline() method (no s!) which reads a single line, the initial value of the Volume, then 3) call the .readlines() method which reads the rest of the lines. Item 2) will be used to set the initial Volume and 3) will be iterated over to represent turning the volume up and down some number of time.
   3. Make sure you return the final Volume object.

Sage Hill Golf Inc. was formed on July 1, 2016, when Matt Magilke purchased the Old Master Golf Company. Old Master provides video golf instruction at kiosks in shopping malls. Magilke plans to integrate the instructional business into his golf equipment and accessory stores. Magilke paid $770,000 cash for Old Master. At the time, Old Master’s balance sheet reported assets of $670,000 and liabilities of $190,000 (thus owners’ equity was $480,000). The fair value of Old Master’s assets is estimated to be $830,000. Included in the assets is the Old Master trade name with a fair value of $12,000 and a copyright on some instructional books with a fair value of $24,000. The trade name has a remaining life of 5 years and can be renewed at nominal cost indefinitely. The copyright has a remaining life of 40 years.

A) Prepare the intangible assets section of Sage Hill Golf Inc. at December 31, 2016.

B) How much amortization expense is included in Sage Hill income for the year ended December 31, 2016?

C)

Prepare the journal entry to record amortization expense for 2017. Prepare the intangible assets section of Sage Hill Golf Inc. at December 31, 2017. (No impairments are required to be recorded in 2017.) (Credit account titles are automatically indented when amount is entered. Do not indent manually. If no entry is required, select "No Entry" for the account titles and enter 0 for the amounts.)

I want you guys to rewrite this lab procedure, and it is fine if it was shorter than this.

An air track was fitted with two photocell bridges, one on each side of the collision region. Each bridge was operating in a gate mode timer that allows the collection of time intervals before and after collision. To ensure that friction and gravity have minimal effects, the track was leveled. Before starting the experiment, we ensured that loss in velocity was no greater than two percent in either direction. To check this, we sent one glider in one direction and noted the time to cross each photocell placed one meter apart. The difference between the two times divided by the time to cross the first photocell was the fraction of momentum that was lost due to friction and gained or lost due to gravity. The track was readjusted accordingly and the check was repeated in the other direction.

The first step in starting the experiment was measuring the masses of the two gliders (i.e. the heavy glider and the light glider). The masses of the gliders were made “heavy” or “light” by adding trimming weights. Then, a series of four collisions (each repeated three times) were conducted

“H” indicates heavy glider, “L” indicates light glider, “Off” indicates that the collision was made elastic by facing the bumpers toward one another, and “On” indicates that the collision was made inelastic by the mounting the “sticky bumpers” on each end (i.e. pin and putty attachments).

Using the memory mode of the photoelectric timers, we were able to collect times for both instances (before and after collision) that that glider past the photobridges. The first data point was our first time point and the second data point was the total of the first and second time point. Therefore, to get the second time, we had to subtract the first time point from the second data point. These times were then used to caluculate the velocities and subsequently the momentum and kinetic energy of both gliders.
