When cells migrate, they exert forces on substrate surfaces. Design an experiment to study the magnitude of the forces.Please provide detailed description for each step. (Hint: label the surface, detect surface deformation, reference: Kong H J et al. PNAS 102:4300 (2005))

A study of the amount of time it takes a mechanic to rebuild the transmission for a 2005 Chevrolet Cavalier shows that the mean is 8.4 hours and the standard deviation is 1.8 hours. If 40 mechanics are randomly selected, find the probability that their mean rebuild time exceeds 8.7 hours. Group of answer choices

This case study concerns a bank's efforts to calculate credit risk scores (These are opposite of credit scores. Higher the value the riskier the customer) A loan officer at a bank needs to be able to identify characteristics that are indicative of people who are likely to default on loans and use those characteristics to identify good and bad credit risks. The loan officer also needs to be able to better quantify an individual’s credit risk level.

Information on 700 past customers is given in the file along with data for the following variables:

Age: customer age in years.

Employment: years that the customer has been with his/her current employer

Address: years that the customer has lived at his/her current address

Income: household annual income (in $1,000)

Debt _to _Income: debt to income ratio (x100)

Risk _Score: Credit risk score (the higher the score, the more risky)

Default _Indicator: an indicator of whether the customer had previously defaulted

Test the hypothesis that the average credit risk score of customers who have previously defaulted on their loans is higher than those who haven’t defaulted on their loans. (Divide the credit risk score into two groups those who previously defaulted and those who didn’t and then compare the two groups.)

You would like to build a regression model to predict the credit risk score based on all the other variables. What is the regression equation?

What is the predicted credit risk score of a customer aged 40, who has been with their employer for 10 years, has lived at the same address for 3 years, has an income of $200,000, debt to income ratio of 2.5 and has previously defaulted on a loan. Will the prediction be accurate? Explain

Compute the coefficient of determination (R2) and fully interpret its meaning.

Interpret the meaning of the coefficients of the independent variables income and address.

Which independent variables significant? Defend your answer.

Go to the Files section and download the AFE_Test file from the Datasets folder. We are interested in a one­tail test described in the following fashion: Ho: u < or = to 200 CFM; H1: u > 200 CFM. At 5% significance level,

we can reject the null hypothesis given the sample information in AFE_Test1.

we can reject the null hypothesis given the sample information in AFE_Test2.

we cannot reject the null hypothesis.

we can reject the null hypothesis given the sample information in AFE_Test1 and AFE_Test2.
