Explаin hоw W.E.B. Du Bоis viewed Wаshingtоn's ideаs and speech as suggesting and even reinforcing limitations for African Americans. Be sure to provide examples from Du Bois. Write in complete sentences. 

Fоr the fоllоwing questions, you will need а periodic tаble.  Use the one found аt this link (don't worry ... Honorlock will be fine if you click this): https://www.fishersci.com/us/en/periodic-table.html   READ CAREFULLY: This question has FOUR parts (A, B, C, and D) and you will need ONE blank sheet of paper (use it wisely).  FOR PARTS A, B, AND C: Write your answers to these parts on your black piece of paper. When you answer each part, write the letter along the left side of the paper and show your solution just under and next to that letter.  SHOW ALL YOUR WORK AS INSTRUCTED IN LABS 1 AND 2. Also, draw a horizontal line across your piece of paper to show where your solution for each part begins and ends. For all atomic weights pulled from the periodic table, round to TWO decimal places.  For all calculations, also round your values and answers to TWO decimal places. Make sure to circle your final answer for each part. When you finish Parts A, B, and C, take a picture of your work with your smartphone and email that image to Dr. Machado at christopher_machado@cuesta.edu.  Make the subject line: [YOUR NAME] Lab 1 Calculations   FOR PART D, TYPE YOUR ANSWER IN THE TEXT BOX BELOW IN COMPLETE SENTENCES!   Part A (6 points) Calculate the number of grams in one mole of cysteine (C3H7NO2S).    Part B (8 points) Magnesium chloride (MgCl2) is a molecule held together by ionic bonds and completely dissociates in solution.  If you are given a MgCl2 solution that has a concentration of 0.5 g/dL, what would be the molarity of that solution?   Part C (8 points) Calculate the osmolarity (in mOsM) of the MgCl2 solution you worked with in the previous question.    Part D (8 points) If you added 5 mL of this solution to a test tube containing 1 mL of human blood and then observed the erythrocytes with a microscope, DESCRIBE what you expect to see in terms of erythrocyte appearance/structure and EXPLAIN HOW that change occurred by comparing this solution to the normal osmolarity of blood.  TYPE YOUR ANSWER IN THE TEXT BOX BELOW, USE COMPLETE SENTENCES AND INCLUDE AS MUCH TECHNICAL TERMINOLOGY AS POSSIBLE!

Intrо. tо  Stаtistics – Test 4 Shоw Working     A die wаs rolled 300 times. The following frequencies were recorded.   Outcome           1        2        3        4        5       6 Frequency        62     45      63      32      47     51   Do these dаta indicate that the die is unfair ? Use a 1% level of significance.                             How do you calculate expected frequencies for cells in a contingency table in a test of independence ? How are the degrees of freedom calculated ?                     Samples of US Congress members were taken. One sample was Democratic and the other Republican. The number of dollars spent on federal projects in each congressperson’s home district was recorded.                                                                    Dollars Spent               Party.              < 5 billion        5-10 billion       > 10 billion            Row Total               Democratic             8                       15                            22                          45               Republican            12                      19                            16                          47               Column Total        20                      34                            38                          92                 Use a 5% level of significance to test whether congressional members of each               political party spent designated amounts in the same proportions.                             Pearson’s correlation coefficient, r, takes values in what range ? If the x and y labels on the variables are switched when calculating r, is it true or false that the value of r will change ?             Consider the following data on study time (x) and subsequent test score ( y). x  20     15  12  10    7    4 y  100   85  75  72   64  40 Calculate Pearson’s correlation coefficient for this data. ( Show working )                               Find the equation of the simple linear regression line for the data in question 5 ( Show working ).                         Calculate and interpret the coefficient of determination for the data and regression from question 5.                     a) For the regression in question 5, find the predicted test score for a      student who studies for 14 hours             b) Is the calculation in a) an example of interpolation or extrapolation ?       Why ?             For the regression line in question 6, interpret the slope and y intercept of the line.                   In a study of 1228 medical malpractice lawsuits, 856 of them were dropped or dismissed. Use a 0.01 level of significance to test the claim that more than half of malpractice lawsuits are dismissed.                                  A sample of 25 workers with employer provided health insurance paid an average premium of $6600 with a sample standard deviation of $800. Construct a 95% confidence interval for the mean premium amount paid by all workers who have employer provided health insurance.                           Interpret the confidence level in question 11.                                 Assume that IQ scores are normally distributed with mean 100 and standard deviation 15 points. If 100 people are randomly chosen, what is the probability that the sample mean will be between 98 and 104 points ?                           It is known that about 64% of people who are murdered knew the person who murdered them.  .  ( p = 0.64 ). 63 unsolved murder cases are examined. Use the normal approximation to the binomial distributionto find the probability that at least 35 of the victims knew their murderers.                           A company allows free returns of it’s products within one week after purchase. An average of 2 out of 10 products sold are returned within one week. Using the Poisson distribution, find the probability that exactly 7 out of 40 products sold on a given day will be returned within one week.                         In a village in Hawaii, about 80% of the residents are of Hawaiian ancestry. Let n be the number people you meet until you encounter the 1st person of Hawaiian ancestry in the village. Write a formula for the probability distribution of the random variable n. Compute the probability that n=4.                   In January in Hawaii, 60% of the days have surf at least 6 feet. At the start of the month, you pick 7 days randomly for vacation. What is the probability that at least 5 of your 7 vacation days have surf at least 6 feet ?                         Roll an unfair die.
