- From the given Chi square, briefly interpret the results/ do the statistical analysis? The p-value from the table is 0.05If you perform a Chi-Squared analysis and determine that your result is greater than the critical value, what would you do? a. Reject H0, accept HA b. Accept H0 c. neitherYou repeatedly draw samples ofn= 100 from a population with a mean of 75 and a standard deviation of 4.5. What sample mean corresponds to az-score of 2.00?

Compare these values to the values obtained Vmax = 525.3 µM/sec Km = 20.70 µM . Which method, nonlinear regression or linear regression, is more tolerant to an experimental error? Note that lower substrate concentrations, which often have the greater error, have a greater effect on the slope of the line in the Lineweaver-Burk plot.
- page - Columbus State Uni X content/2622738/viewContent/50155728/View + Calculating the Value of Chi-Square Once you've defined the null hypothesis (and know what you're testing!), you can finally calculate the chi-square value based on your observed data and the expected distribution. There are many statistical software packages and free web-based applications that will automate the calculation for you, but it's important to understand the calculation to understand the meaning of the calculated value. Here, we'll walk through it using a calculation table. This is Mendel's historic data for the F2 generation of monohybrid cross for flower color. Recall that he expected to see in the F2 generation a ratio of 3 purple : 1 white. Chi-square calculation for data from a monohybrid cross with an expected 3 purple : 1 white ratio.

What is the importance of sample size and choice of test organism in studies involving probabilities? 3. Differentiate mean, variance, and standard deviation. 4. What does a relatively small standard deviation indicate?The electrophoresis gel shown below had a 4th lane (cut off and not shown) which contained 7 proteins of known molecular weight. A plot of these proteins was made with log MW on the y-axis and migration distance (cm) on the x-axis.The equation for the linear regression line is: Y = -0.1 X + 4.79If the distance between the well and the 3rd band of the Red sample is 4 cm, what is the approximate MW, expressed in daltons, of the protein at that location?
