Emissions of sulfur dioxide by industry set off chemical changes in the atmosphere that result in "acid rain." The acidity of liquids is measured by pH on a scale of 0 to 14. Distilled water has pH 7.0, and lower pH values indicate acidity. Normal rain is somewhat acidic, so acid rain is sometimes defined as rainfall with a pH below 5.0. A sample of 105 rainwater specimens had mean pH 5.43; standard deviation 0.54; and five‑number summary 4.33, 5.05, 5.44, 5.79, 6.81. (a) Compare the mean and median and also the distances of the two quartiles from the median.

a) Does it appear that the distribution is quite symmetric? Why?

a. The mean is almost identical to the median, and the quartiles are similar distances from the median. This suggests that the distribution is reasonably symmetric.

b. The third quartile is closer to the median than the first quartile is. This indicates that the third quartile may have been pushed down by a right‑hand skew in the distribution.

c. The mean is a relatively resistant measure, while the median isn't. Therefore, the median gets pulled further away from the direction of a long tail. Since the median is lower than the mean, we conclude that the distribution has a right hand tail.

d. The median is a relatively resistant measure, while the mean isn't. Therefore, the mean gets pulled further away from the direction of a long tail. Since the mean is lower than the median, we conclude that the distribution has a right‑hand tail.

(b) If the distribution is really ?(5.43,0.54), what proportion of observations would be less than 5.05? (Enter your answer rounded to four decimal places.)

proportion:

If the distribution is really ?(5.43,0.54) , what proportion of observations would be less than 5.79? (Enter your answer rounded to four decimal places.) proportion: Do these proportions suggest that the distribution is close to Normal? Why?

a. No, because the Normal distribution has a lower first quartile and a lower third quartile.

b. Yes, because the quartiles are very close to the quartiles of the Normal distribution.

c. No, because the Normal distribution has a higher third quartile and a higher first quartile.

d. These proportions do not provide information about Normality.

Determine the changes in length, breadth, and thickess of a steel bar which is 5m long, 40mm wide and 30mm thick and is subjected to an axial pull of 35kN in the direction of its length. Then find the volumetric strain and final volume of the given steel bar. (Take E= 200000 N/mm2 and poisson ratio (v) = 0.32)

1. A) Based on your knowledge of the physical, physiological and behavioral changes that take place during domestication (particularly in the Farm Fox Experiment, but in other domesticated species as well) provide FOUR brief (1-2 sentences, max) pieces of evidence to suggest why domestication may have had adaptive value in early populations of “proto-dogs” and thus was favored by natural selection. Include comparative evidence and experimental evidence in your answers.

B) In many species, behavioral adaptations reflect neural adaptations. For example, various species exhibit cortical magnification of ecologically important regions of the somatosensory cortex. Define cortical magnification and provide an example of it in one species

That is all the info I have

Thinking of a pandemic and how it changes everything, let's say that you have the money to invest, which type of companies do you invest on and which do you avoid? What are the characteristics of a company that may thrive during a pandemic?

explain why?

In the evolution of the eukaryotic cell, these cells have key changes that include which of the following: a) These cells reproduce by copying their DNA perfectly each generation. b) They have their DNA in the nucleoid area. c) have adapted the mesosome membrane system of the prokaryote to form a nucleus and an endoplasmic reticulum. d) each new type of new eukaryote cell has its mRNA unchanged from its original mRNA,

Since the SUTA rates changes are made at the end of each year, the available 2019 rates were used for FUTA and SUTA.

Note: For this textbook edition the rate 0.6% was used for the FUTA tax rate for employers.

Example 5-5

Sutcliffe Company had taxable wages totaling $87,500. During the year, the company paid some of its state contributions after the January 31 cutoff of the following year. The penalty for tardiness is shown in the following calculation of the firm's net FUTA tax:

Example 5-6

Yeldon Company has a $70,000 federal and state taxable payroll and has earned a reduced state tax rate of 4 percent. If none of its state tax payments are timely, the FUTA tax calculation is as follows:

If Yeldon Company had made its SUTA payments before the due date of Form 940, the credit for the payments (4%) and the additional credit (1.4%) would have provided a total credit of $3,780 and a FUTA tax savings of $280.

Peroni Company paid wages of $170,500 this year. Of this amount, $124,000 was taxable for net FUTA and SUTA purposes. The state's contribution tax rate is 3.1% for Peroni Company. Due to cash flow problems, the company did not make any SUTA payments until after the Form 940 filing date. Compute the following; round your answers to the nearest cent.

a. Amount of credit the company would receive against the FUTA tax for its SUTA contributions
$__________

b. Amount that Peroni Company would pay to the federal government for its FUTA tax
$________

c. Amount that the company lost because of its late payments
$_______

1. Since the SUTA rates changes are made at the end of each year, the available 2019 rates were used for FUTA and SUTA.

   Note: For this textbook edition the rate 0.6% was used for the net FUTA tax rate for employers.

   Example 5-10

   Karlson Software Company is located in State H, which enables employers to reduce their contribution rates under the experience-rating system. From 2006 to 2015, inclusive, the company's total contributions to state unemployment compensation amounted to $14,695. For the calendar years 2016 to 2019, inclusive, the contribution rate for Karlson was 2.7%.

   The contributions of each employer are credited to an account maintained by the State Unemployment Compensation Commission. This account is credited with contributions paid into the account by the employer and is charged with unemployment benefits that are paid from the account. Starting January 1, 2020, the contributions rate for all employers in State H will be based on the following tax rate schedule:

   Reserve Ratio	Contribution Rate
   Contributions falling below benefits paid	7.0%
   0.0% to 7.9%	5.5%
   8.0% to 9.9%	4.5%
   10.0% to 11.9%	3.5%
   12.0% to 14.9%	2.5%
   15.0% or more	1.5%

   The annual payroll for calculation purposes is the total wages payable during a 12-month period ending with the last day of the third quarter of any calendar year. The average annual payroll is the average of the last three annual payrolls. The SUTA tax rate for the year is computed using the information available (benefits received and taxes paid) as of September 30 of the preceding year.

   The schedule below shows the total payroll and the taxable payroll for the calendar years 2016 to 2019.

   	Calendar Year
   	2016		2017		2018		2019
   	Total Payroll	Taxable Payroll	Total Payroll	Taxable Payroll	Total Payroll	Taxable Payroll	Total Payroll	Taxable Payroll
   First Quarter	$12,000	$12,000	$11,000	$11,000	$13,000	$13,000	$10,000	$10,000
   Second Quarter	11,750	11,750	11,500	11,400	12,750	12,700	9,300	9,300
   Third Quarter	12,500	12,250	12,750	12,400	12,200	12,000	9,350	9,350

   Unemployment benefits became payable to the company's qualified unemployed workers on January 1, 2006. Between that time and September 30, 2019, total benefits amounting to $15,100.90 were charged against the employer's account. Compute:
