QUESTION 1 A cytotoxic T cell encounters a kidney cell displaying a pathogen's antigen on a MHC 1 molecule. What is likely to happen? The cytotoxic T cell will bind to the kidney cell and trigger nearby B cells into producing plasma cells. The cytotoxic T cell will not bind to the kidney cell The cytotoxic T cell will bind to the kidney cell and release chemicals to destroy the cell The cytotoxic T cell will bind to the kidney cell and initiate phagocytosis to eat the kidney cell QUESTION 2 What are the disadvantages of using an attenuated virus?

Use a t-test to test the claim about the population mean µ at the given level of significance a using the given sample statistics. Assume the population is normally distributed. Claim: ? ? 7800; x = 0.10 Sample statistics: x = 7500, s=430, n=20 C. $H_0: \mu ? 7800$ $H_a: \mu > 7800$ What is the value of the standardized test statistic? D. $H_0: \mu ? 7800$ $H_a: \mu = 7800$ The standardized test statistic is 3.12. (Round to two decimal places as needed.) What is the P-value? P=0.002 (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. A. Reject $H_0$. At the 10% level of significance, there is not enough evidence to reject the claim. B. Reject $H_0$. At the 10% level of significance, there is enough evidence to reject the claim. C. Fail to reject $H_0$. At the 10% level of significance, there is enough evidence to reject the claim. D. Fail to reject $H_0$. At the 10% level of significance, there is not enough evidence to reject the claim.
