Which of the following correctly describes the sequence of events in angiogenesis? O Release of VEGF-A→ Filopodia formation → Migration of stalk cells → Tip cell formation → Capillary lumen creation Migration of stalk cells → Release of VEGF-A → Tip cell formation → Capillary lumen expansion → Filopodia degradation OVEGF-A binds to VEGFR-2 → Tip cell selection → Filopodia extend toward VEGF source → Stalk cell proliferation → Connection of tip cells to form new capillary lumen Tip cell migration → VEGF-A release → Formation of stalk cells → Filopodia retraction → Lumen formation Filopodia formation → Release of VEGF-A→ Selection of tip cell → Migration of endothelial cells New capillary connection

You wish to test the following claim ($H_a$) at a significance level of $\alpha = 0.001$. For the context of this problem, $\mu_d = \mu_2 - \mu_1$ where the first data set represents a pre-test and the second data set represents a post-test. $H_o: \mu_d = 0$ $H_a: \mu_d \ne 0$ You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain pre-test and post-test samples for $n = 17$ subjects. The average difference (post - pre) is $\bar{d} = 27.6$ with a standard deviation of the differences of $s_d = 49.4$. What is the appropriate test procedure for this scenario? z-test t-test What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value =

This project can bring in a profit of $ \$ 50 $ billion with a $ 50 \% $ probability of success and can fail with a $ 50 \% $ probability. This failure would mean a loss of $ \$ 10 $ billion in costs. a. Calculate the expected profit for the project. b. Assuming the manager is risk averse, can this project be done? Explain? 10. If a consumer has a utility function: $ \mathrm{U}=52 \mathrm{X}-2 \mathrm{X}^{2}+116 \mathrm{Y}-5 \mathrm{Y}^{2} $ a. Show the law of diminishing marginal utility in that function. b. This customer's income is 350 , price X is 5 , price Y is 2 . Write the budget constraint equation for this consumer. 11.

Design an ER diagram for an E-commerce Platform described below: Very important notes: 1- Make sure to suggest the necessary attributes for each entity and relationship if any. 2- Make sure to illustrate the cardinality and participation constraints for each relationship. 3- Remember that you have limited time, so please be reasonable and specific, do not think out of the box to invent attributes that you don't really need for the provided scenario. The Scenario: Sellers can list products, customers can place orders, and payments are processed for successful transactions. Each product is listed by one seller. Each order is placed by one customer, but a customer can place multiple orders. Each order can have multiple products, and each product can be part of multiple orders. Each order is associated with one payment, and each payment is for one order.
