Homework Answers
this will be analused by paired t test
as before-after study was being set up
....................
we will find the difference of before-after
then mean of these difference,D̅ =
then std dev of difference ,Sd
std error , SE = Sd / √n
t-statistic = (D̅ - µd)/SE
and then compare this tst stat with critical value

Suppose you want to test to see if there is a difference in steady-state hemoglobin levels (measured in gdL) for patients with different types of sickle-cell disease. The two diseases for which you will study are: HB SS - Commonly referred to as "sickle cell anemia" (I will abbreviate this as X) HB SC - Commonly referred to as "sickle cell disease" (I will abbreviate this as Y) Although both have their complications, HB SS is referred to as the...

Question 1 Tests comparing 2 population means can be: surveys experiments both surveys and experiments Question 2 If all the experimental units are identical (ex: clones), you will set up the study as: CRD Block Design Question 3 a 2 sample t-test still has which normality assumption(s)? The population is normal or n is greater than 30 both populations are normal or both sample sizes are greater than 30 Question 4 When you block by some variable in a block...

You want to test the effects of different antibiotics on protein synthesis. You set up three test tubes to carry out protein synthesis in vitro. After letting protein synthesis proceed, you add the following to the tubes: Tube A - No antibiotic Tube B - Antibiotic B Tube C - Antibiotic C (1) Please state the results shown below. (2) Given the results, which step of translation may be most likely affected by Antibiotic B? Explain your answer. (3) Give...
You are conducting a study to see if the proportion of stocks that went up is is significantly less than 0.3. You use a significance level of α = 0.01 .
Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.A sample of 80 stocks traded...

Programming in C with comments/steps
1. Overview The purpose of this assignment is to give you some experience with writing functions that take in arguments and return values, as well as writing a program that consists of multiple files. This assignment also requires the use of a switch statement, in addition to more practice with printf& scanf declaring variables, using loops, and using logical expressions. For this assignment, you will prompt the user in the main function to enter their...

5. You want to see if smoking marijuana has any effect (positive or negative) on memory span. You pre-test subjects on the memory span measure, then pair up subjects who have the same memory test score. After matching the subjects, you conduct the actual experiment. One member of each of the 15 pairs of subjects is assigned at random to smoke a marijuana cigarette; the other member of each pair is assigned to smoke a cigarette that doesn't contain any...
