1. you will read a list of internet logs from a notepad.
2. then you will extract the following.
- a host (e.g., '146.204.224.152')
- a user_name (e.g., 'feest6811' note: sometimes the username is missing! In this case, use '-' as the value for the username.)
- the timme a request was made (e.g., '21/Jun/2019:15:45:24-0700')
- the post request type (e.g., 'POST /incentivize HTTP/1.1' note: not everthing is a POST!)

Your task is to convert this into a list of strings:
"host :146.204.224.152"
"user_name: feest6811",
"time :21/Jun/2019:15:45:24 -0700",

Question 2: A study was undertaken to compare the waste-generating behaviour of residents in four remote, isolated communities: Pétaouchnok, Malakazoo, Erehwon, and Naschmere. 20 households were randomly selected from each of these communities, and the average daily garbage output measured over a specified period of time. The data obtained is shown in the table below (values in kg/day of waste per capita): Pétaouchnok Malakazoo Erehwon Naschmere 2.3 4.5 1.1 1.7 3.3 3.0 4.1 1.1 3.3 2.3 2.0 0.0 4.4 1.8 3.9 3.1 2.6 3.3 2.1 3.9 3.3 5.2 2.7 3.4 5.3 3.7 5.0 3.3 0.0 3.1 2.6 2.9 3.7 2.2 4.3 3.1 2.5 5.0 5.4 3.1 1.9 5.0 2.7 1.3 2.9 1.8 0.7 1.7 1.0 3.0 2.8 1.8 4.4 4.6 2.8 1.9 3.6 4.0 3.1 2.1 3.7 1.7 4.1 3.2 3.4 3.1 3.7 2.6 4.0 3.2 4.8 1.9 2.5 2.5 3.0 2.7 3.7 1.7 3.7 2.9 a) Calculate the grand mean, as well as the sample mean and variance for each town, for average per capita waste in kg/day. b) At LOC = 95%, what would you conclude about whether or not there is any difference in garbage generation rates across these four towns? Use the critical-value method. c) Using the p-value method, determine if your conclusion from Part (a) would be different for any common values of LOC.

C. Effect of adding a strong acid base to an amphoteric hydroxide

1. Obtain approximately 20.0 mL of 1.0 M zinc nitrate solution and place it into a 150 mL beaker.

2. Add 6 M sodium hydroxide (with mixing), in a drop-wise fashion, until a reasonable amount of solid appears.

3. Divide the mixture from step 2 into approximately two equal portions. (This mixture contains the amphoteric hydroxide.)

4. To one of the two portions, continue to add 6 Msodium hydroxide (with mixing) until you see a distinct change in the mixture. Note how much sodium hydroxide solution was added. (Recall: 20 drops  1 mL)

5. To the other portion, add 6 M nitric acid (with mixing) until you see a distinct change in the mixture. Note how much nitric acid solution was added. Dispose of the solutions in the appropriate waste receptacle

results for part c are as follow

first portion the solution got thick and was cloud llike.

the second portion

obervation after adding 1mL HNO3------------------ the precipate broke apart to smaller pieces onnce a good amount was added

QUESTION the context of part C of this experiment, explain what an amphoteric hydroxide can do that:

• acetic acid can’t do

• aqueous ammonia can’t do

• sodium chloride can’t do

1. My mom has been in pain due to a pinched nerve on her spine. She was advised to do some injections to manage some of the pain. I decided to do a little research on my own to learn whether other patients feel any major difference after the injections. A detailed survey is presented to 25 patients and results were recorded in a scale of 1 to 10 to mesure the level of pain after the injection. Use the sample data to construct a 90% confidence interval for the mean pain level for the population (assumed normal) from the following data: 7.4, 0.0, 2.1, 8.1, 7.2, 7.0, 3.2, 6.9, 0.5, 4.3, 2.2, 8.6, 7.8, 8.8, 5.9, 7.9, 1.8, 2.8, 1.7, 8.9, 9.4, 9.6, 4.3, 8.2 and 1.0.

Iconic memory is a type of memory that holds visual information for about half a second (0.5 seconds). To demonstrate this type of memory, participants were shown three rows of four letters for 50 milliseconds. They were then asked to recall as many letters as possible, with a 0-, 0.5-, or 1.0-second delay before responding. Researchers hypothesized that longer delays would result in poorer recall. The number of letters correctly recalled is given in the table.

(a) Complete the F-table. (Round your values for MS and F to two decimal places.)

(b) Compute Tukey's HSD post hoc test and interpret the results. (Assume alpha equal to 0.05. Round your answer to two decimal places.)

The critical value is  for each pairwise comparison.

Which of the comparisons had significant differences? (Select all that apply.)

Recall following no delay was significantly different from recall following a one second delay.The null hypothesis of no difference should be retained because none of the pairwise comparisons demonstrate a significant difference.Recall following a half second delay was significantly different from recall following a one second delay.Recall following no delay was significantly different from recall following a half second delay.

1. In order to determine the size of a home-heating furnace, it is necessary to estimate the heat loss during the coldest day in winter. Provide the rates of heat loss per unit surface area for the following surfaces commonly encountered in house construction. You may assume an inside air temperature of 25°C, an outside temperature of -5°C, and heat transfer coefficients of 20 Wm-2K-1 and 5 Wm-2K-1 between air and the outside and inside surfaces, respectively. The thermal conductivities of glass and air are 1.4 and 0.026 Wm-1K-1, respectively.

a. A 3 mm-thick single-pane glass window.

b. A double-pane glass window consisting of two 3 mm-thick panels separated by a 6 mm-thick layer of stagnant air.

c. A composite wall consisting of a 10-cm-thick brick exterior (k = 1.0 Wm-1K-1), a 10-cm-thick layer of loosely packed glass fiber insulation (k = 0.043 Wm-1K-1), and an inside gypsum plaster wall (k = 0.17 Wm-1K-1) that is 1 cm thick.

d. Workmen installing a wall of the design described in part (c) are asking for a premium to install a vapor barrier on the plaster wall to prevent moisture from diffusing out of the house and condensing in the glass fiber insulation. If the dew point of the moist air in the house were 10°C would you pay the premium? Why?

The null hypothesis of no difference should be retained because none of the pairwise comparisons demonstrate a significant difference.

Are cigarettes bad for people? Cigarette smoking involves tar, carbon monoxide, and nicotine (measured in milligrams). The first two are definitely not good for a person's health, and the last ingredient can cause addiction.
